On the morning of June 12, Santa Monica authorities received reports of a prowler in the area. When police responded to the call, they encountered a man who claimed he was waiting to meet up with a friend. Upon searching the man's car, which had Indiana plates, the officers found weapons, ammunition and materials used in pipe bombs. KTLA reports that there was at least one assault rifle found in the car. 

The Santa Monica officials have said that there is no known connection between the Orlando shooting and the Santa Monica arrest at this time. 

According to the L.A. Times, the city plans to increase security at the Pride parade. The parade was scheduled to start at 10:45 a.m., and a moment of silence was held around that time, according to KTLA. 

This arrest comes just hours after a shooting at an Orlando gay nightclub that left 49 people dead, making it the deadliest mass shooting in U.S. history.
