Norwich — Police are investigating a Monday night incident in which a man said he had been shot at but later became uncooperative, according to Lt. John Perry.

Perry said the incident occurred just after 11:30 p.m. Officers, he explained, were on the scene of an unrelated incident on Prospect Street when they heard what they thought were gunshots. It was around the same time that a man approached one of the officers and said he was being shot at.

As officers began to ask questions, the man became uncooperative.

Perry said officers so far have not located evidence that anyone or anything was struck in the possible shooting. Officers also have not located any shells or other ballistic evidence.

Because of the lack of evidence, police haven’t yet pinpointed a crime scene or developed any suspects.

The investigation is active. Police are asking anyone who saw or heard anything near the area Monday night to call them at (860) 886-5561.
