A 50-year-old gas station clerk was shot Wednesday morning after confronting a man stealing a bottle of water, police said, an incident that came on the heels of another late Tuesday that damaged two cars.

The clerk’s shooting occurred at 3:58 a.m. Richie’s Shell at 1001 Cambridge St., in the Wellington-Harrington neighborhood. The victim is a 50-year-old, who was taken to a local hospital with non-life-threatening injuries after the shot grazed his foot and has since been released.

The clerk confronted a man taking a bottle of water, and the man got a bag from a car, pulled out a gun and shot at the clerk. The driver of the vehicle sped off in one direction and the shooter fled on foot, said Jeremy Warnick, director of communications and media relations for Cambridge police.

Police found the weapon in a black plastic bag on Inman Street. The driver of the vehicle was also found, stopped and taken into the Cambridge police station for questioning.

The shooter has been identified, police said, and is being looked for.

It’s the seventh shooting incident in Wellington-Harrington and The Port neighborhoods since March 31, although this confrontation – with an injury – is different from most of the shooting incidents reported in that two-month stretch of time.

The sixth such incident: gunshots that occurred at approximately 11:53 p.m. Tuesday at Washington Elms and Harvard Street that, like in the recent past, resulted in no reported victims – aside from two unoccupied vehicles parked next to each other that were damaged by gunshots.

There were reports of a large group of people fighting a half-hour before the gunshots, and witnesses saw two vehicles – described as sedans – leaving the scene at the time of the shooting, police said.

In the investigation that followed, police made an arrest of a Cambridge teen, for the second gun-related arrest in five days. The suspect is not described as the shooter in this case, however.

In the police telling:

Multiple individuals in the area of the gunshots were stopped and questioned. One of the individuals – Abigail Riskey, 19, [of Columbia St.] – was asked to remove items out of her purse to ensure there were no weapons in her possession. One of the items was something heavy inside of a piece of cloth. Officers unknotted the cloth and observed a box with a pictured handgun and bullets on the cover. Upon further inspection, the box contained numerous rounds of 9MM ammunition. Riskey did not provide a license to carry ammunition or a firearm and was placed under arrest for possession of ammunition without an FID card. The ammunition and cloth were taken as evidence.

The number of incidents led to the calling of a community discussion from 6 to 8 p.m. Wednesday at the Pisani Center, 131 Washington St., in The Port with Bard, Mayor Marc McGovern and City Manager Louis A. DePasquale planning to be on hand to answer citizens’ questions about the city’s response to the shootings and its strategies for reducing gun violence.
