HARTFORD (AP) — A suspect has been arrested in the Hartford nightclub shooting that left one dead and four others injured, police said in a tweet Monday.

Police arrested the suspect for the shooting of 28-year-old Marquis Treadwell, of Hartford, who was killed following an argument early Sunday at the Majestic Lounge, a nightclub in the city's south end.

The suspect faces charges for Treadwell's killing as well as various assault and firearm charges, according to the Hartford police tweet, which said more information will follow.

Police have not released the names of the other victims, which include two males and two females ranging in age from 19 to 34 years old. Officials say one of the female victims was shot nine times.

Police said earlier that the shooter or shooters and the victims apparently knew each other.

Mayor Luke Bronin said officers were stationed outside the club because of previous problems there and heroically ran inside when they heard the gunfire, possibly saving other lives.

He said Sunday that illegal handguns were involved in the shooting and that city officials will be assessing what steps they can take to prevent violence at the club in the future.

“Hartford Police Officers who were at the club responded immediately, running in the direction of gunfire, and their heroic efforts may have prevented further loss of life,” Bronin said in a statement.
