A “Jackass”-style stunt Sunday night in Hollywood drew a huge response from emergency personnel and wound up getting the stunt’s perpetrator arrested.

USA Today reports that Stephen Glover, better known as Steve-O, was arrested after allegedly climbing a crane to inflate a balloon version of a killer whale as a protest against SeaWorld. Glover is one of the stars of the “Jackass” TV series and movies.

“Dozens of police and fire rescue people had to respond Sunday night to a construction site on Sunset Boulevand where [Glover] climbed a crane at least 100 feet high, Los Angeles police Lt. Michael Ling told reporters,” the story reports. “At the top of the crane, Glover, 41, inflated a large killer whale balloon with the words ‘SeaWorld Sucks’ on it and lit fireworks. Eventually he climbed down and was arrested.”
