One person was killed early Saturday morning and Arvin Robertsseveral were injured after shots targeting people at a gathering were fired from a vehicle in Lynn, Massachusetts, officials said.

Nobody was in custody yet after the shooting injured six other people, two critically, at about 2:20 a.m. Saturday, Essex County District Attorney Paul Tucker told reporters. Police responded to multiple 911 calls about shots fired and injuries. They found a "chaotic scene," Tucker said.

Police didn't give a possible motive or the number of people they believe fired shots at the gathering, but said it was not a random act.

"This is a terrible act of violence that’s torn at the fabric of this neighborhood and this city," Tucker said.
