A male nurse has been charged after a teenager told police that she was sexually assaulted after coming in for treatment at a downtown hospital earlier this week.

The alleged incident happened at around 5 a.m. on Sept. 6.

A 19-year-old woman was at the emergency department at Mount Sinai Hospital for treatment when she was sexually assaulted, police said.

Police did not say why the woman had come to the emergency department or whether the suspect was meant to be treating her at the time of the alleged assault.

In an email to CP24.com, the hospital said that patient safety is a top priority.

“We are working in full cooperation with Toronto Police Services and will do everything possible to ensure a full and timely investigation,” the statement read. “The individual has been placed on a leave of absence pending a full investigation.”

The hospital also encouraged any patients with concerns to reach out to its patient relations department.

The College of Nurses of Ontario confirmed Wednesday that it is also investigating the alleged incident.

Yan (Arn) Xie, 34, has been charged with sexual assault.

He was granted bail during a brief court appearance on Tuesday evening.

Police say they are concerned there may be more victims.

Anyone with information is being asked to contact police at 416-808-5200 or call Crime Stoppers anonymously at 416-222-TIPS (8477).
