A man has been arrested on his way to the Los Angeles gay parade with ammunition, rifles and explosives in his car.
The man, still unidentified, was arrested on Saturday evening in Santa Monica.
Police said the incident is "unrelated" to the shooting of at least 50 people in Orlando on Saturday.
The mayor of Los Angeles has said the gay pride march will continue as planned and they will hold a moment of silence for the victims in Florida.
As reported by the LA Times, the Santa Monica police got a call of a suspected "prowler". They intercepted a man who said he was waiting for a friend.
When they inspected his car, they found the weapons and arrested him.
The mayor of West Hollywood, Lauren Meister, told reporters on Sunday morning that the city was on a heightened alert, and was working with the police and FBI.
Eric Garcetti, the mayor of Los Angeles, said that citizens will "not shrink back into the closet".
"This is a society we love broadly and openly," he said.
