Danger! Candidate teacher arrested in investigation into 'sexualized images shared online' after stealing $300,000 from 96-year-old blind man.

Classes ended early for students at a Brooklyn private school after their teacher was taken away in handcuffs amid allegations he shared sexualized images on social media.

Winston Nguyen, 37, who taught mathematics at St Ann's School, a private school in Brooklyn Heights, had previously participated in the television quiz show Jeopardy!.

Nguyen, who has taught at the $60,000-a-year school since 2020, has not been charged with any offense but is still a suspect.

Nguyen has also found himself in legal jeopardy in the past.

In 2019, Nguyen was jailed for four months on Rikers Island after stealing $300,000 from a blind 96-year-old man and his 92-year-old wife, both of whom have since died.

Further investigations are underway into Nguyen's alleged conduct, according to the Kings County District Attorney's Office.

The school confirmed he was under investigation for “disseminating intimate images via social media.”

“Upon his arrest on Thursday, he was immediately placed on leave by the school and remains on leave,” a spokesperson said.

School principal Kenyatte Reid wrote to parents informing them of the arrest while asking families who may have further information about Ngyuen's conduct to come forward.

“This incident is very disturbing for all of us. We are proud of our incredible faculty and a learning environment rooted in trust,” Reid wrote.

Seven years ago, Nguyen got into trouble with the law again and was arrested after stealing $300,000 while working as a home aide for an elderly couple, the Stolls.

Nguyen pleaded guilty, serving time in prison and probation while also being ordered to repay the money.

Just three years later, Nguyen was teaching at a private school even though administrators were fully aware of his criminal record.

“A non-violent criminal record cannot prevent employment,” the St. Ann spokeswoman said.

“The school carefully and judiciously evaluates an applicant’s potential suitability for the school.

“We are fully cooperating with law enforcement in their efforts, and at this time we are working to help our students process this news.”

Parents of children at the exclusive school appeared troubled by the arrest and Nguyen's criminal history.

“What does the verification process look like? What does the process look like in the background,” one parent asked The Daily Beast.

“The idea that he was someone close to my children… it's terrifying. I see him as a manipulator and a scammer,” the parent added.

Famous Brooklynites who have attended St. Anns in the past include Girls creator Lena Dunham, actress Jennifer Connelly, artist Jean-Michel Basquiat, and Maya Hawk, the daughter of Ethan Hawke and Uma Thurman.

When Nguyen worked as a home health aide, he stole nearly $300,000 from the elderly couple, Bernard and Florence Stoll, both in their 90s.

He was hired in 2009 to assist the blind man and his wife with their daily tasks.

He used the money to pay for expensive ballet tickets, Broadway shows, and trips to Florida with his friends, all at the expense of his unsuspecting employer.

He worked for the couple for six years until he was finally arrested after the couple's daughter-in-law discovered he had been stealing from them.

Nguyen used the couple's bank account and credit cards to make $100,000 in purchases and cash withdrawals.

He wrote checks for $200,000 himself, then opened lines of credit using their information to the tune of $35,000.

He was able to hide the theft by changing the address on the couple's bank statements to his own home address. He then falsified the statements to remove any fraudulent purchases.

All calls from banks requesting money were also blocked after Nguyen placed a bar on the couple's phone.

Following the discovery of the theft, Nguyen pleaded not guilty to 32 counts of grand theft, possession of stolen property and identity theft.
