A Trumbull homeowner may have fired a gun near some Bridgeport youths about 9 p.m. on Halloween, according to police.

Officers responding to a report of shots fired near Leffert Road found a group of youths running toward Unity Road. The youths told police someone was shooting a gun on Foster Avenue. Officers later found several empty handgun casings near the intersection of Leffert Road and Foster Avenue, in the Nichols section of town.

Police interviewed witnesses and residents, and believe there was a dispute between the youths and a resident, who fired a gun to scare the youths, who may have been tampering with several parked vehicles in the area.

Police are continuing to interview residents and collect evidence. Anyone with information on this incident is asked to contact Trumbull Police at 203-261-3665, or through the anonymous tip-line on the department’s website, trumbull-ct.gov/police.
