"Jackass" star Steve-O was arrested Sunday night after drawing emergency responders to a Hollywood construction site where he climbed a crane towering at least 100 feet above ground in a protest against Seaworld, police said.
Officers who initially responded to the site were unsure whether the stunt performer needed to be rescued from the crane on Selma Avenue at Gower Street, but firefighters were preparing a cushion in case of a fall, according to the Los Angeles Police Department.
A heavy rescue crew, several fire trucks and ambulances were sent to the scene about 8 p.m.
The stunt performer, whose real name is Stephen Glover, was streaming video of himself on Facebook climbing the crane.
Police said Glover inflated a large killer whale balloon with a message about SeaWorld, and at one point set off fireworks from the tip of the crane.
On Saturday, Glover posted a photo of himself holding an inflatable whale on his official Instagram account and announced that he would be performing a "big dangerous stunt."
Last year, he was slapped with a $239 fine after changing a 5 Freeway sign in San Diego to read "SeaWorld Sucks." Glover said his protest was in response to controversy over the 2013 documentary "Blackfish," which criticized SeaWorld's treatment of killer whales.
During the incident Sunday, he wrote in a Facebook post, "Anyone wanna bail me out of jail?"
Glover climbed down just before 9 p.m. and was taken into custody, police said.
As of 9:45 p.m. he had not been booked, but police said he could face several charges including conspiracy to commit a crime, trespassing, setting off explosives - the fireworks - within city limits without a permit and filming for personal gain without a permit.
"Some of the resources on this hoax could have been devoted to a real emergency," Fire Department spokeswoman Margaret Stewart told The Associated Press.
Glover's representative didn't immediately respond to a request for comment. A call to SeaWorld has not been returned.
Glover was held at the LAPD's Hollywood Division station before his release early Monday. A court date was scheduled for Aug. 31, according to jail records.
