Witnesses said cars at the sideshow were spinning out and doing donuts in the parking lot in honor of what would have been the "Fast and the Furious" actor's 45th birthday. Walker died in a car crash in 2013 at age 40.
Some security guards got into a scuffle with members of the crowd and video shows damage to their vehicle, including a cracked windshield.
"It's alarming when we see this in the video. The behavior of the people that are gathering at these car meets wanting to beat other people up or just damage property - it's just not acceptable," Lt. Travis Tibbetts said.
West Covina police confirm they are investigating the incident as felony vandalism and assault and battery to the two security officers.

It was actually the second city the rowdy group had gathered in for the night. They had originally gathered in Montebello, but were chased out of the area.
Authorities hope the videos help people identify the assault suspects.
"I think the video is pretty clear and I think there's someone out there that can help us identify who those suspects are that damaged that car and then hurt those security officers," Tibbetts said.
The West Covina Police Department asks anyone with information to call (626) 939-8688.
