Police are investigating the nonfatal shooting of two people at around 8:18 p.m. Monday at Washington and Windsor streets in The Port neighborhood. There were no immediate arrests.

The two known victims have been taken to local hospitals after being treated on-scene. The injuries are serious, but not believed to be life-threatening, said Jeremy Warnick, director of communications and media relations for Cambridge police.

Preliminary information indicates that the victims were shot while sitting in a car, Warnick said. “The car was damaged and a number of casings have been recovered,” he said.

It was the first gunfire incident of the year that police were called to city streets to respond to; in 2022 year there were 14 gunfire incidents, with the final one coming Dec. 16. Two incidents last year had victims, for a total of three people shot in Cambridge in 2022. None were fatal. Four of the gunfire incidents last year took place in The Port.

This incident follows gunfire Wednesday in which police shot a 20-year-old man they said had been holding a large knife, self-harming and running around the neighborhood. The man, Sayed Faisal, died at Massachusetts General Hospital.

Anyone with information about the Monday incident is asked to call (617) 349-3300 or make contact anonymously.
