LEWISTON — Some 20 police officers and detectives responded Monday afternoon to gunshots on Bartlett Street.

Police were gathering shell casings across the street from the Masjidu Salaam Mosque at 240 Bartlett St. around 3:30 p.m. after reports of gunshots.

Detective Sgt. Corey Jacques said at the scene that further information was not available.

“We’re getting to witnesses now and just trying to figure out what happened,” Jacques said.

It was not clear if anyone was injured.

Police were seen with K-9 units in the Pierce Street area, though it wasn’t confirmed if that was related to the Bartlett Street investigation.

Bartlett Street was closed from The Italian Bakery at 225 Bartlett St. to 243 Bartlett St.

Masjidu Salaam Mosque has been the site of several shootings among a larger issue of gun violence in recent years.

Lewiston Mayor Carl Sheline acknowledged the troubling nature of shootings in the mosque’s area.

“I appreciate our police department’s quick response,” Sheline said. “We’ve now had several shootings recently in this immediate vicinity,  which is deeply troubling.

“Witnesses and residents who have any information need to come forward and speak to a detective or use the anonymous tip line. Cooperation and communication is critical to solving crimes and holding those responsible accountable,” he said.

Anyone with further information is asked to contact the Lewiston Police Department at 207-513-3001.
