"Jackass" star Steve-O has been arrested for climbing a crane in Hollywood in a protest against Seaworld.

Los Angeles police said 41-year-old Stephen Glover drew dozens of emergency responders to a construction site where he climbed a crane towering at least 100 feet.

Lt. Michael Ling said that when Glover reached the top, he inflated a large killer whale balloon with the words "Seaworld Sucks" on it and lit fireworks or a firecracker.

He climbed down on his own and was taken into custody.

Ling said because the first responders were unsure whether Glover needed to be rescued, several ambulances and fire trucks were sent to the scene. Firefighters prepared a cushion in case of a fall.
