Kathmandu: At least 22 people have been killed in shootings in Lewiston, Maine, a law enforcement official said, based on initial information gathered by first responders at three locations.

That figure could rise. Dozens more were injured, said the person, who spoke on the condition of anonymity. Authorities were investigating multiple active shooter events late Wednesday, as a suspect remained at large, the Androscoggin County Sheriff’s Office said on social media “We are encouraging all businesses to lock down and or close while we investigate,” the sheriff’s office said.

Lewiston City Councilor Robert McCarthy, whose home is located half a mile from where one of the shootings happened, recalled the incident as “a real scary event.”

“We locked all the doors. We grabbed the guns,” he told CNN’s Abby Phillip Wednesday night. “We’re just waiting to hear that they catch the individual or individuals that did this.”

He said his “hearts and prayers go out to everybody involved and we’re thinking of you.”

Two businesses have been associated with the “active shooter incident” by Lewiston police: Schemengees Bar & Grille, an arcade-style restaurant on Lincoln Street, and a bowling alley formerly known as Sparetime Recreation, now Just-In-Time Recreation, on Mollison Way.

The FBI Boston Division said in a statement that it is coordinating with law enforcement partners in Maine following the shootings this evening in Lewiston and stands “ready to assist with any available resources they need.”

The division urged the public to “remain vigilant” and described the situation as “very fluid.”

The Androscoggin County Sheriff’s Office and the Lewiston Police Department released security footage of the gunman wielding what appears to be an AR-style rifle inside Just-In-Time Recreation in Lewiston.
