At least 10 people have been shot in an apartment complex in San Bernardino, California, with reports stating that three of them are in an "extremely critical" condition.

San Bernardino spokesperson, Captain Richard Lawhead, released a statement, saying: "We got a call about 10:45 p.m. for shots fired. We found 10 victims down at the scene. Three are extremely critical."

Lawhead added that multiple handguns and rifles were fired by suspects who reportedly fled the scene. The officer added that the shootout occurred at an apartment complex at 1277 E. Lynwood Drive on Sunday night.

KTVN-TV in Los Angeles reported that police officials have set up a large perimeter around the crime scene after the shootout.

San Bernardino is nearly 90km east of Los Angeles and police officials  believe that there was "an exchange of gunfire." An officer said: "I can tell you multiple shots were fired, I don’t want to guess how many.

Lawhead said that officials believe that people had gathered to possibly play a game of dice when the shooting occurred and said that it was a "chaotic scene." He added that detectives, as of Monday morning, do not have a clear suspect or motive for the shooting.

A local resident, Alysa Marie, who lives in the area, while talking to CNN, said: "My brother-in-law could hear bullets flying past our house, he was outside at the time of the shooting."

Another resident, Eduardo Rivas, said: “I heard around four shots, then what sounded like a motorcycle speeding off, after that just a continuation of gunshots.”
