BOSTON — A masked crew that stabbed a man on a Roslindale sidewalk before dawn on Saturday is still on the loose, and Boston police have released surveillance photos of three suspects in a bid to identify them.

The attack happened around 6:10 a.m. on July 11 in the area of 500 Canterbury Street, police said in a community alert Monday. An altercation ended with the victim suffering non-life-threatening stab wounds. He was later dropped off at a local hospital, where officers responded to a radio call for a person stabbed — meaning the department's first sign of the crime came from the emergency room, not the scene.

Detectives are looking for three individuals caught on camera at the scene. One is described as a light-skinned male, roughly 5'3", wearing a black "shiesty"-style mask, blue jeans and a fanny pack.

Two other suspects appear in the released images — one in a black t-shirt and beanie with visible tattoos, and one in a gray hoodie and sweatpants with his face covered. A third figure in a red top is partially visible behind them in multiple frames.

Investigators also released a photo of the vehicle they believe carried the crew away from the scene: a gray 2020 Honda Civic with Massachusetts registration 6BTK53, registered in South Easton.

District E-13 detectives are asking anyone who recognizes the suspects, the vehicle, or has any information about the incident to call them at (617) 343-5628. Anonymous tips can be sent to the CrimeStoppers tip line at 1-800-494-TIPS or by texting "TIP" to CRIME (27463). Boston police say the identities of anonymous tipsters will be protected.
