Steve-O has been arrested for climbing a crane.
The Jackass star scaled the 30-metre construction crane in Hollywood as a protest against the marine mammal park, Sea World, wearing a 'Blackfish' T-shirt - from the documentary made against the park - and holding an inflatable orca.
The strange incident was documented by the TV personality in a series of bizarre videos posted to his Facebook page, in which he ascended the crane and indicated he was going to jump off, saying, "It's stunt time".

According to the Los Angeles Times newspaper, several worried witnesses called for emergency services as they believed he was going to commit suicide, with more than 80 firefighters arriving on the scene to set up an air cushion around the structure in an attempt to protect him if he jumped.
