In another gun incident at the port, a person is injured across the street following an earlier disturbance on July 4

A man from the Port district of Cambridge was taken to hospital on Tuesday with life-threatening gunshot injuries, police said.

Just before 9:13 p.m. Tuesday, gunshots were heard at 131 Harvard Street, bringing police to the scene, Cambridge Police Chief of Operations Pauline Wells said in an 11:35 p.m. email. Scanner reports said ShotSpotter gunshot detection technology did not go off, but witnesses said they heard three to five shots and that they may have come from a vehicle that subsequently sped onto Portland Street.

The victim was a man between 40 and 50 years old with a gunshot wound to his left hip, according to police and scan reports. He was taken to Massachusetts General Hospital in Boston. Two cars were also hit by gunfire.

A crime scene was set up at the location, known as Port Landing Apartments, and several shell casings were found in the area, police said. Investigators remained on scene for hours “to continue the investigation very intensively,” Wells said. At 10:29 p.m., more gunshots were heard on Washington Street, based on a call from a hotline but could not be confirmed and officers suspected it may have been fireworks.

It was Cambridge’s seventh gun incident of the year (not including an accidental discharge by a police officer) and the third since June 26 to occur in The Port area of ​​the city, police said. Two of the incidents this year involved people being struck by gunfire, and three people were injured in total.

In the last gun incident on July 4, police responded at 10:05 p.m. and found shell casings in “multiple areas” around Greene-Rose Heritage Park — one block west of Tuesday’s incident. Scanner reports said a witness saw a man with a handgun running toward Broadway, another block north of Dickinson.

Anyone with information about Tuesday’s shooting is asked to contact the police Special Investigations Unit anonymously, either at cambridgepolice.org/TIPS or by calling (617) 349-9151.
