LEWISTON — A tactical police force surrounded an apartment house on Blake Street Friday afternoon in response to a shooting in the area the night before.

Police shut down a section of Walnut and Blake streets at about 2 p.m. as a state tactical team approached a four-story apartment house at 158 Blake St.

Police working from an armored vehicle parked in the street searched both in and around the building as throngs of onlookers watched from nearby blocks.

The police operation was related to a round of gunfire reported in the area of 141 Pierce St. at about 11 p.m. Thursday.

One woman who lives in the area reported “about a dozen rapid fire shots right outside my living room window.”

Other witness reported seeing a young man fleeing the area in the moments after shots were fired. It appeared, those witnesses said, that the suspect had been firing at another man who also fled the scene.

When police responded, they found that two vehicles and at least one building had been struck by gunfire, although there was no immediate indication that anybody had been injured.

Police Lt. Derrick St. Laurent said witnesses reported seeing a young man, a juvenile, running from the scene of the shooting and into the apartment house at 158 Blake St.

Those reports were backed up by video surveillance footage of the area reviewed by police as they investigated the shooting, St. Laurent said.

Because the suspect was known to be armed, Lewiston investigators called for help from the Maine State Police tactical team before searching the building.

The search on Friday did not produced the gunman, police said, but evidence was seized and the investigation is ongoing. Because the suspect is a teen, he wasn’t named.

It was the second time inside a month that police have searched 158 Blake St. in connection to gun violence, St. Laurent said.

In August, two teens who live in the building were arrested on charges of conspiracy to commit murder after police intercepted threats made from a youth center in South Portland.
