NEW HAVEN, Conn. (WTNH) — New Haven police responded to a “chaotic scene” Thursday morning after shots were fired at the 7-Eleven on Foxon Boulevard in New Haven, according to authorities.

Officers responded to the convenience store just before 2 a.m. for the report of gunshots being fired into the building. Police determined that there were no gunshot victims. One person suffered minor cuts to their face from shattered glass.

According to eyewitnesses, police said a BMW was parked in the lot, followed by a grey Honda Civic a short time later. Several passengers from the Honda Civic entered the store, armed with handguns and dressed in dark clothing, witnesses told police.

While inside the store, the BMW driver pulled up near the entrance, and one passenger got out and fired shots at the people inside the store, resulting in an exchange of gunfire, police said.

Authorities found four fired cartridge casings in the parking lot, plus several projectiles and casings inside the store.

Everyone involved fled the scene, police said.

Anyone with information is asked to call the New Haven Police Department Investigative Services Division at (203) 946-6304 or the department’s anonymous tip line at 866-888-TIPS (8477).
