The downfall of Bam Margera has been captured on camera during his wild visit to Finland, with the Jackass star photographed being taken away in a police van and later brazenly urinating in a public park.

Margera, 36, was behaving erratically around Helsinki during the trip this month which culminated in a night where he sat helplessly on the sidewalk yelling before police helped him stand up and carted him off in their van.

The photographs show the depths of of the troubled television star's plight, with him also shown talking to Helsinki police in a separate incident in a car on the day he was photographed urinating in the park.

Margera has struggled with substance abuse since the death of his close friend and co-star Ryan Dunn five years ago, saying he feels 'completely lost' in the wake of the tragedy.

Last year, Bam had reportedly been sober for three months after quitting booze following a history of benders in recent years. He had received help from a doctor he met on reality TV.

Dunn lost his life in a horror 130mph smash in his Porsche 911 GT3 on a Pennsylvania highway in 2011. He was later found to have been drunk at the time.

'It was the worst phone call I ever got in my life waking up to that,' Bam said at the time.

He was fined £500 in Glasgow in 2013 after verbally abusing a member of staff at a hotel following an Eminem concert in the city.

During the trip to Helsinki this month, the star was also photographed peeing in a public park on a day when he was also visited by police again while sitting in a car drinking with friends.
