PITTSFIELD — One man was injured in a Saturday night fight at Zen's Pub on Tyler Street, according to Pittsfield police.

The disturbance, which happened shortly before midnight, was followed by two separate shooting incidents. Sgt. Gary Belknap said shots were fired around midnight on Tyler Street, about 50 yards away from Zen's, and there was a subsequent ShotSpotter activation around 12:30 a.m. at the corner of Onota and Linden streets. It was unclear if the incidents were connected.

When police officers arrived at Zen's, Belknap said they found a man bleeding from his arm. It didn't appear to be a gunshot wound, he said. The man was transported to Berkshire Medical Center for treatment.

Belknap said officers found shell casings near the corner of Onota and Linden streets, and a male suspect fled the area on foot.

There was also a shooting in the plaza near Zen's last month that resulted in minor injuries. Ryan Aulisio was arrested and has pleaded not guilty to a charge of attempted murder in that incident.
