TORRANCE, Calif. (CNS) — A crowd estimated at 1,000 juveniles engaged in a brawl Sunday at the Del Amo Fashion Center in Torrance, prompting local police officers and those from neighboring departments to rush to the shopping mall.

The city of Torrance issued a statement warning of police activity at the mall, advising the public to avoid the area.

Officers were called about 4 p.m. to the mall in the 3500 block of Carson Street in response to “a large group of juveniles fighting amongst themselves,” Torrance police Sgt. Ron Salary told City News Service.

The crowd of youths was so large that officers with the Gardena, El Segundo, Manhattan Beach and Los Angeles police departments rushed to the scene, as well as Los Angeles County sheriff’s deputies.

It was unclear what prompted the violence.

Officers confirmed through a witness that a firearm was discharged but they could not locate any victims, Salary said.

As of 7:30 p.m., officers were still working to clear out the juveniles, he said.

Businesses in the area were not evacuated, Salary said. No injuries were reported. Information about arrests was not immediately available.
