A “high chance” of a mass shooting in Hollywood was thwarted Tuesday by police seizing a cache of guns and ammunition in a high-rise apartment where several rifles were pointed toward a nearby park, the Los Angeles Police Department said.

Braxton Johnson was taken into custody Tuesday after he allegedly made violent threats involving weapons to security staff at the apartment building and people outside, the agency said the following day.

A search of Johnson’s apartment turned up two assault rifles and high-capacity ammunition magazines, all of which are illegal in California, as well as three handguns, a sniper rifle, a shotgun and more than 1,000 rounds of ammunition.

Investigators have not said whether they uncovered any additional evidence of a plot to target the park, or Johnson’s motive in pointing the rifles toward the area. Details about the threats he allegedly made Tuesday have also not been released.
