A 36-year-old Dorchester man was arrested and arraigned on Monday for allegedly filming boys in the restrooms at Boston Latin School, according to US Attorney Andrew Lelling’s office.

Eric Tran Thai was charged in federal court with five counts of sexual exploitation of children. He is accused of filming people in men's restrooms in other locations, including Boston College.

Police located and spoke with Thai, after a Feb. 27 report of surreptitious filming in Boston College, later arresting him on state charges in Middlesex County Superior Court.

The US Attorney's office alleges that while speaking with police, Thai admitted to “taking some pictures” of a man in the stall next to him without the man’s consent and engaging in similar activity for about a year. A search of his bag after arrest uncovered several covert camera devices, including faux smoke detectors, a water bottle containing a small cube recording device, and a pair of sunglasses outfitted with a built-in camera, officials said.

Law enforcement searched Thai's home on March 1, seizing around 26 computer hard drives, 20 thumb drives, 27 covert and regular cameras, 14 computers, iPads, and cell phones, and multiple SD and Sim cards. They contained several folders labeled: BU, MIT, Harvard, Northeastern, Bunker Hill, Boston Latin High School, and several different malls, airports, and foreign country locations, officials said.

Prosecutors allege that the around 45 videos contained in folders labeled “Boston Latin High School” showed male students "in various states of dress using the urinals and stalls in a Boston Latin High School boys’ bathroom. The videos appear to have been created on approximately 10 separate dates between February and December 2017," the US Attorney's office said in a press release.

Thai is shown in these videos sitting in a bathroom stall at Boston Latin High School recording covertly.

The Boston Globe reports that Thai is a former BLS student.

“Headmaster Skerritt and I are horrified by the allegations that were brought to our attention by law enforcement,” BPS Interim Superintendent Laura Perille in a statement to the Globe. “Safety is always our top priority, and we strive every day to make sure our students are learning and thriving in safe, welcoming, and supportive schools.”

Each of the five seal exploitation of children charge calls for a mandatory minimum 15 years and up to 30 years in prison, though sentences are “imposed by a federal district court judge based upon the U.S. Sentencing Guidelines and other statutory factors,” Lelling’s office said.
