Steve-O taped himself up to a billboard in Hollywood as part of a publicity stunt on Thursday morning, prompting a response from the Los Angeles Fire Department.

The “Jackass” star and television personality, known for his wild stunts and pranks, began livestreaming himself this morning on his YouTube channel. Steve-O was duct taped to a billboard in the 1700 block of Cahuenga Boulevard that promoted his upcoming multimedia special, Gnarly.

“I’m attached to a billboard right now … and want to emphasize that a team of real professionals rigged everything safely,” he assured fans in an Instagram post. “There is zero chance of me falling, and it’s important to me that we not waste any valuable city resources on this.”

But at 9:35 a.m., LAFD personnel and local law enforcement responded to bring down the well-known prankster, calling the situation “an apparent single patient behavior emergency,” according to a Fire Department alert.

At least one lane of Cahuenga was closed during the operation, impacting traffic in the area, according to LAFD.

Firefighters used a ladder to help him off the billboard and he was safely down by around 10:20 a.m., according to Sky5 video.

Steve-O, clad only in a diaper at the time, was then placed in a wheelchair and examined by fire personnel, the aerial footage showed. He was released soon after.

The Los Angeles Police Department told KTLA that Steve-O had rented the billboard and, as he wasn’t trespassing, no crime was committed.

The performer, whose real name is Steven Glover, was previously arrested in connection with a different aerial stunt in Hollywood in 2015.

On Aug. 9 of that year, Steve-O climbed an approximately 100-foot-tall construction crane and shot fireworks off of it in an apparent protest against SeaWorld, which he streamed live on his Facebook page.

He was sentenced to 30 days in jail and temporarily ordered to stay out of Hollywood after pleading no contest to two misdemeanors.
