A man was stabbed on Blue Hill Avenue in Roxbury Saturday night and suffered life-threatening injuries, according to Boston police.
The incident took place at around 10 p.m. near 49 Blue Hill Ave., said Officer James Kenneally, a department spokesman.
A stretch of Blue Hill Avenue was closed to most traffic just before midnight. Only emergency vehicles, including a van from the state medical examiner’s office, were allowed in.
A police cruiser with flashing blue lights blocked the street. Yellow police crime tape cordoned off the area from Winthrop Street to Huckins Street. Police walked up and down the sidewalk near the scene with flashlights.
Residents who tried to access the area were told by police to walk around the block. A number of cars that approached the scene had to turn around.
Lyndell Harley, 22, who lives nearby, said violence is unusual for the area of Blue Hill Avenue near Winthrop Street. The last time there was a strong police or fire response was for a fire a couple of years ago, he said.
“I’m kind of shocked,” Harley said after taking a video of the scene on his phone.
He pointed toward nearby Dudley Street. “You usually hear gunshots like crazy on Dudley,” he said.
The incident is under investigation, police said.
No further information was available.
