Boston nurse to be arraigned Monday for inappropriately touching two minors

BOSTON, July 24, 2026 -- A Hopedale man and former Boston Children’s Hospital nurse will be arraigned Monday July 27 in Suffolk Superior Court for sexually assaulting two teenage boys in his care, Suffolk District Attorney Kevin Hayden announced. 

JOHN TAM, 33, was indicted by a grand jury earlier this month on four counts of indecent assault and battery on a person fourteen years or older and four counts of indecent assault and battery on a patient by a health care provider.  

Hayden urged parents whose children may have encountered Tam at Boston Children’s Hospital or at his prior workplaces, including Beth Israel Deaconess Medical Center, UMass Memorial Medical Center Worcester campus and UMass Memorial Medical Center Marlborough campus, to contact authorities if they have any suspicions that their children may have been assaulted. 

“We are concerned that these may not be isolated incidents and we want to assure parents that any information they provide will be thoroughly and sensitively investigated,” Hayden said.  

On September 19, 2022, a fifteen-year-old boy underwent surgery on his chest at Boston Children’s Hospital, located at 300 Longwood Ave. He was administered anesthesia during the surgery, and awoke to find his nurse, later identified as John Tam, inappropriately touching his genitals.

On January 2, 2025, Boston police responded to Boston Children’s Hospital for a report of a sexual assault. The minor victim had recently undergone surgery under anesthesia. His nurse, John Tam, was responsible for performing vital checks after the surgery concluded. Tam told the victim’s mother to get her car and drive to the entrance so the patient could be discharged. Tam dressed the victim, took him to the first floor, and brought him into a single-stall bathroom despite the victim not indicating he needed to use the restroom. Tam then sexually assaulted the victim for approximately eight minutes, including fondling his genitals and offering to pull up pornographic material on his phone to make the victim erect, before wheeling him outside to his mother’s vehicle. When the victim’s mother became aware of the situation, she immediately alerted hospital staff.

Officers reviewed security footage and observed Tam wheeling the victim to a bathroom and exiting nine minutes later.
