Emergency services were called to the scene yesterday when Steve-O from Jackass scaled a huge crane to protest against Seaworld. 

There were serious concerns for his safety when he climbed 30metres up the massive structure in California. At the time, he was carrying an inflatable killer whale called Shammy – a reference to the park's most famous attraction, Shamu. 

He was arrested for trespassing – though fans have already begun a GoFundMe page to raise cash for his bail. 

In advance, Steve-O had posted to Facebook saying: "This is Shammy.

"We're going to do a big dangerous stunt in Los Angeles tomorrow that will probably get me in a lot of trouble, and you can watch it happen via a live stream, right here on Facebook, starting at exactly 7pm PST. See you then."

 

Seaworld has come under a lot of criticism in recent years with plenty of people alleging that its whales and other mammals are not kept in the best of care. As a result, it seems that visitor numbers and profits are falling.

Steve-O later posted another photo saying: "Did I mention that I'm really high in the air? Hearing sirens now. Check the video I posted at 7pm to see what I'm doing. I'll stream live again soon for the stunts."

Incredibly, in order to maximise publicity for the stunt, he furthermore let off fireworks at the top of the crane. 

Indeed, in his final video of the evening he acknowledged: "We definitely have their attention," as he looked underneath him and saw loads of police cars pulling up on the road below. 

And at the end of his final video he said: "Alright! Can I zoom in this f***ing Facebook… That is a lot, A LOT, of f***ing fire trucks. I mean come on!"

Some time later he posted on Facebook saying "Anyone wanna bail me out of jail?"

Last year, the actor and stuntman was slapped with a €220 fine after changing a motorway sign in San Diego to read: "SeaWorld Sucks".
