美國佛羅里達州一名大學化學系華裔博士生李旭明（Xuming Li）對樓上住客投毒，被揭發後遭刑事檢控及開除學籍，並被遣返回國。
鄰居發出噪音可以投訴，但美國佛羅里達州一名大學化學系華裔博士生李旭明（Xuming Li）竟對樓上住客投毒，被揭發後遭刑事檢控及開除學籍，其代表律師班特納（Adam Bantner）證實，李旭明已被移民部門遞解返回中國。
《紐約郵報》（New York Post）周三（6日）報道，李旭明持學生簽證到美國攻讀博士學位，他透過門縫向樓上住客阿卜杜拉（Umar Abdullah）注射在大學實驗室調製的化學物質。事件起因在2022年6月，阿卜杜拉與懷孕妻子搬到李旭明住所樓上的公寓，李旭明是與妻子及兩名小孩同住，起初兩家人相處得不錯，阿卜杜拉的妻子誕下女兒，李旭明還送贈一條裙子道賀。
不過，李旭明某日突然發短訊向阿卜杜拉投訴他一家人發出太大噪音，導致經常被吵醒，因此要求晚上11時後放輕腳步和別移動家俱。阿卜杜拉坦言收到短訊時有點吃驚，更沒想到其後情況會惡化。
由於李旭明的短訊內容越來越不客氣，來自孟加拉、從事科技行業的阿卜杜拉於是進行模擬測試，他邀請物業管理員一同到李旭明家，然後叫妻子在樓上走動及跳躍，甚至移動家俱，但均沒有聽到任何聲響；即使李旭明自行購買設備再測量分貝，結果也是一樣。
及後阿卜杜拉開始聞到一股怪味，一家人無故頭暈和嘔吐，一歲的女兒更不停地流淚和咳嗽，遂在家門口安裝防盜鏡頭，才發現李旭明透過門縫以針筒注射化學物質，李旭明隨即被捕。阿卜杜拉由於害怕會遭到報復，事發後已搬走。

A Chinese chemistry student who was caught injecting opioid solution through the gap of his neighbor’s door has been deported, the New York Post reported.
Xuming Li, a chemistry PhD graduate, is believed to have placed strong opioid painkillers methadone and hydrocodone, mixed with an unknown noxious element through his neighbors door during a dispute over noise.
Li was arrested after Umar Abdullah set up a secret camera in a plant pot outside his home on Palm Springs Boulevard, Tampa, and caught him in the act.
The 36-year-old chemistry researcher was charged with possession of a controlled substance, battery assault against the homeowners, and aggravated stalking.
However Li’s attorney, Adam Bantner told the Post that Li had been deported back to China by US immigration officials.
The recent University of Southern Florida graduate was caught on camera after the family planted a hidden lens in a potted houseplant outside their home
Umar Abdullah, who lives in the home, said he noticed an ‘obnoxious’ smell and he, his wife and baby daughter began vomiting so he planted a camera outside
Sources told the publication that the legal case against him was now largely defunct.
Li had pleaded not guilty to several felony charges, including battery and possession of a controlled substance.
When Li did not make it to his scheduled hearing on Monday due to his deportation, a judge issued a warrant for his arrest that would only activate in the unlikely event of his return to the US.
Li had been studying at the University of Southern Florida (USF), but Abdullah said the school ‘took very swift action by bringing an expulsion sanction’ against him following the incident.
Concerned father Abdullah revealed in the summer how along with vomiting, dizziness and severe headaches, his family suffered hair loss, and they found ‘clumps of hair’ on their baby girl’s pillow several times in June this year.
‘Our baby was losing her hair,’ he told DailyMail.com. ‘In that one month, we noticed our baby’s unusual hair in the shower.
‘We Googled and realized babies don’t experience hair loss, and we noticed our hair in the shower as well.
‘We can’t prove that it was linked, but we feel that it was because of the chemicals.’
Li lamented over losing sleep and hearing noise from Abdullah’s apartment

Abdullah added that he was shocked by what his secret camera recording revealed because Li had seemed like a ‘regular guy’ and even a ‘friendly’ neighbor who often stopped to chat in the hallway.
He told the DailyMail.com that Li is also a father to two young children – though he has never seen Li with the kids despite regularly seeing his wife taking them to the playground.
Their relations were rosy in August 2022, when Abdullah’s baby was born, with Li sending him a text to ask how his wife and newborn daughter were doing.
Abdullah told the DailyMail.com Li even came to their door with gifts for their daughter, and congratulated them by text on their ‘really adorable girl’.
But his noise complaints began days later, with Li asking if the family could ‘walk slower’ to prevent him hearing their footsteps at night.
Text messages seen by DailyMail.com show how Li regularly complained about minor noises – from the toilet seat moving to someone dropping their phone on the ground.
Meanwhile, Abdullah offered to buy cushioned footwear to reduce the impact of their footsteps, and to visit Li’s apartment so he could see what it sounded like for himself.
But tensions reached a head in March this year when Abdullah’s family visited, and Li called the police on them within 15 minutes of their arrival, complaining about the noise of their luggage scraping across the floor.

‘We were shaking,’ Abdullah told WFLA. ‘We can’t imagine that he is coming and doing something’
Three months later, Li sought his revenge by planting a noxious mix of chemicals at the family’s front door while they were away at an Ohio conference.
When they returned in early June, they were plagued by an ‘obnoxious’ smell and soon began feeling sick while losing clumps of hair.
Abdullah believed the smell to be coming from his air conditioning unit or his water heater, but plumbers and officials who investigated found no issues.
His landlord even replaced the heater and had his air ducts and vents cleaned – but the chemical smell persisted.
Desperate to find out what was plaguing his family, Abdullah called the fire department who sent in a Hazmat team – but their tests drew a blank.
‘I was sniffing the place like a dog,’ he said.
The sniff test led him to his doorway, where he found a small crack in the corner.
Only now beginning to suspect some form of tampering had taken place, Abdullah set up a hidden camera in a potted plant outside his door.
His daughter became sick again, prompting Abdullah to check the footage – and he was shocked by what he saw.
‘We were shaking,’ he said. ‘We can’t imagine that he is coming and doing something.’
The footage showed Li, wearing casual tracksuit bottoms, crouching and appearing to place something beneath their door.
Horrified, Abdullah adjusted the camera angle from door-level to eye level to catch what Li was doing in the moments before.
This time, his footage appeared to show Li extracting a syringe, filling it with clear liquid, and injecting it into the crack in Abdullah’s door frame.
The terrified father immediately got his family out of the house and called police.
He rushed his family to hospital in a panic – an experience he described in his victim impact statement for a hearing against Li at the USF, resulting in his expulsion.
‘My heart was wrenching as my head felt like it was spinning,’ he said in the statement seen by DailyMail.com.
‘My wife and I rushed to the emergency room, clutching our precious daughter, fearing the worst.
‘Seeing her tiny hand with an intravenous catheter, enduring those painful pokes and tests, tore me apart inside.
‘Her innocent face, contorted with pain and fear, filled my soul with unbearable anguish.
‘All because of that heartless criminal, Mr Xuming Li, whose actions had brought such misery upon our little angel.
‘My eyes welled up with tears as I held my daughter close, praying for her safety.
‘The thought of her having to bear this suffering because of someone’s sinister deeds was too much to bear.’
Abdullah said he was relieved the tests showed ‘nothing critical’, but his doctor advised his family to inform all their future consultants about the incident in case they suffered ‘elevated blood platelet levels and any potential long-term effects’.
‘We are still living in constant trauma, haunted by the memories of that dreadful day,’ Abdullah said.
‘Now, after a month, almost every other day, we still clean and disinfect the door area with disinfectant, hoping to rid ourselves of the any poison that the monster injected for us to inhale.
‘Since the incident, we’ve lost our sense of security, and we can’t leave our home alone.
‘My wife and daughter used to enjoy their mornings out while I work, but now they’re paralyzed by fear and do not dare to go just by themselves.’
Chemistry whiz accused of trying to poison Florida neighbor deported to China
Published Dec. 6, 2023, 4:38 p.m. ET
A former Florida chemistry student charged with injecting poisonous toxins underneath his neighbor’s front door has been deported to China and is unlikely to face charges in the US, The Post has learned.
Xuming Li drew international headlines earlier this year after he was caught on camera crouching down and pumping noxious materials into Umar Abdullah’s apartment amid an ongoing noise dispute.
Sources said Tuesday Li had been deported back to his native land by American immigration officials and that the criminal case against him was largely defunct.
Li’s attorney, Adam Bantner, confirmed his departure.
The budding scientist — who was expelled from the University of South Florida after the shocking case went viral — had pleaded not guilty to several felony raps, including battery and possession of a controlled substance.
But Li failed to appear at a scheduled hearing Monday due to his deportation, prompting a judge to issue a warrant for his arrest that would only activate in the unlikely event of his return to the US.
Li had been in the country pursuing his doctorate in chemistry on a student visa — and mixed the substances in his university’s lab.
Abdullah said he and Li had a cordial relationship after he first moved into an apartment directly above the chemist back in June of 2022.

Li — who lived with his own wife and two small kids — even gifted the Abdullahs a dress to mark the birth of their daughter.
But the relationship began to corrode after Li began sending Abdullah text messages grousing about noise coming from his apartment.
“By the way, could you please walk slower and not move furnitures after 11 pm?” Li asked. “The big sound always wakes us up.”
Abdullah, a tech professional from Bangladesh, said he was taken aback by the note but didn’t foresee an escalation.
But Li’s complaints grew increasingly caustic, prompting Abdullah to organize a simulation to test just how disruptive his family’s movements were.
While his wife and child remained upstairs in their apartment, Abdullah and a building staffer met Li in his residence and strained their ears.

Abdullah said he told his spouse to make every movement imaginable, from marching around the apartment to rearranging furniture to jumping.
Abdullah said there were few perceptible sounds, and he thought the feud would soon fizzle.
But Li persisted, buying a decibel-reading device in attempt to quantify the alleged racket.
“Again, there was barely anything,” Abdullah said.
A few months later, Abdullah said he and his family began experiencing sudden bouts of nausea and dizziness.
During one outbreak, Li reached out again.
“Can you walk softer?” he wrote. “We couldn’t sleep last night.”
Li had been a student at the University of South Florida before his arrest.

Abdullah told him about the sicknesses in his reply.
“Sorry to hear that,” he responded. “My house is full of eye burning gas from the water heater. I was hurriedly opening my windows and doors and that was causing panic footsteps probably.”
Li — who would soon be charged for pumping an opioid mix into his neighbor’s home — gave a terse reply.
“I heard it from your landlord,” he said. “Sorry to hear your situation.”
Suspecting Li of somehow being behind the mystery maladies, Abdullah set up a hidden camera that caught Li crouching down and emptying a syringe full of chemicals underneath his front door.
He was arrested soon after.
Abdullah — who moved out of the apartment and said he feared retribution from Li — did not immediately respond to a request for comment on the deportation.
