An Indiana man was arrested in Santa Monica early Sunday morning for carrying ammunition, three automatic rifles, and the ingredients for a pipe bomb in his car. The man, identified by Santa Monica police as James Wesley Howell, told police that he was on his way to the LA Pride parade, scheduled to start at 10:45 a.m.

Officials said they did not believe Howell had any connection to the shooting in Orlando that occurred earlier in the day. Fifty died at a gay nightclub in the Florida city, including the shooter. A representative from the FBI Los Angeles office told press there was no known credible threat in the Los Angeles area.

The city of West Hollywood was on heightened alert this morning, and City Councilor Lindsey Horvath said in a statement that security efforts were being stepped up around the parade and festival today.

"We intend for this parade to go off and the festival afterwards to go off without a hitch," acting LA County Undersheriff Neal Tyler said.

The parade began with a moment of silence. Attendees held printed signs saying "I am Pulse," referring to the Orlando incident.

West Hollywood mayor Lauren Meister and LA Mayor Eric Garcetti called for solidarity in the face of the shooting.

"Our hearts will be heavy but our resolve will be strong," Meister said.

"We all wanted to be here this morning, but we didn't want to be here under these circumstances," Garcetti said. "All of our hearts today are with Orlando."

This story has been altered based on new reports saying the man did not indicate to authorities that he planned to harm the LA Pride Festival.
