Watch Ant McPartlin step out of his crashed mini before failing a breathalyser test

This is the moment Ant McPartlin leaves the wreckage of his car, looking shaken and unsteady on his feet, following the three-vehicle smash which led to his arrest, in exclusive footage obtained by the MailOnline.

The TV presenter appears dazed as he climbs out of his £26,000 John Cooper black Mini, which smashed into two other cars and injured a three-year-old girl.

The incident in Richmond, west London, saw McPartlin arrested on suspicion of drink-driving after failing a breathalyser test.

This afternoon his agent revealed that Ant & Dec's Saturday Night Takeaway – the ITV show he co-hosts with lifelong friend Declan Donnelly - is cancelled so McPartlin can 'check into rehab'. 

The video shows a passer-by approach and speak to the startled McPartlin. The telly favourite appears to nod as he stumbles and holds on to his car door.

The 42-year-old looks down at the damage to the front of his car, before he walks out. Both front seat airbags appear to have been triggered by the impact of the crash. Other pedestrians look on in shock after witnessing the smash, which involved the celebrity's black Mini, a green Mini and a maroon BMW.

McPartlin, who is worth £60million, spent most of the night in police custody, before he was released under investigation and returned home at 3am today. 

The star has endured a troublesome year with his battle with painkillers addiction and the breakdown of his marriage to Lisa Armstrong.

A statement on behalf of Ant & Dec confirmed McPartlin was taking a break from his on-screen duties, where he hosts on ITV with Declan Donnelly.

It said: 'Ant has decided to go back into treatment and step down from his current TV commitments. 

'He has spoken with Dec and ITV today and asked for time off for the foreseeable future. As such "Saturday Night Takeaway" will not be going ahead this Saturday.' 

An ITV spokesman said: 'ITV has taken a joint decision with Ant and Dec's team not to broadcast Saturday Night Takeaway this weekend.

'We will be reviewing options for the last two episodes of the series (March 31 and April 7) which would not feature Ant who is taking time off to seek treatment. We very much hope that he gets the help that he needs.' 

A witness to the crash told MailOnline: 'There were two cars travelling along Lower Richmond road - a green Mini Cooper and an X5 which was about much further back. 

'A black Mini Cooper shot round the corner but instead of turning left went straight across the road and smashed into the green Mini.

'It was a bad crash but the black Mini Cooper still travelled on and crashed into the BMW behind which had done an emergency brake. There was a woman and her young son in there.

'Airbags deployed in the black Mini and a lady came out of the passenger seat. No one came out of the driver seat initially.

'The lady in the BMW came out but her son stayed in the car. The family in the Mini Cooper also came out and an Asian lady ran and screamed at the driver of the black Mini who was still inside. A passerby was asking her to calm down and checked on everyone to see if everyone was OK.

'People were checking that everyone was alright. There was a lot of confusion cos the horn remained blaring on the car for ages. Everyone was dazed by it all.

'When the driver came out, he just shouted intermittently at his mother but didn't speak to anyone else until the police arrived shortly. There were two dogs in the Mini.'

Just seconds before the crash, McPartlin was seen driving his John Cooper special edition car along Sheen Lane, after taking his dog for a walk in Richmond Park, southwest London, just before 4pm yesterday.

CCTV footage captured the TV presenter just seconds before he reached a mini roundabout on Lower Richmond Road and crashed into a green Mini and maroon BMW - injuring a three-year-old girl.

The video emerged shortly after his mother, Christine Woodhall, was seen for the first time, leaving his London home, after the arrest.

McPartlin failed a roadside breathalyser test - just 20 hours after appearing live on TV hosting Ant & Dec's Saturday Night Takeaway. He was arrested by police and spent 10 hours in custody.

The Metropolitan Police confirmed the TV presenter, who has had a troublesome year with an addiction to painkillers and the breakdown of his marriage, had been released 'under investigation'. 

He was spotted arriving home just before 3am this morning, following his arrest. 

His mother, Ms Woodhall, who is believed to have moved in with her son when the troubled star was struggling with painkillers, was seen today getting into the back of a black Mercedes van which parked as near to the house in Chiswick, west London, as possible. 

A driver was seen removing several bags from the boot before Ms Woodhall, looking tired and shaken, jumped in the back before she was whisked away. 

The troubled television personality allegedly crashed his black Mini after losing control of his vehicle on a roundabout, which veered into the opposite side of the road and collided with a green Mini, which had a young girl and couple inside. 

Celebrity publicist Simon Jones visited the home of McPartlin today. Jones, who is known to represent Little Mix, One Direction stars and McFly, spent around 90 minutes at the home for crisis talks.

He arrived in a Range Rover with two of his team members and refused to answer questions about how McPartlin was.

Several hours earlier an Audi A5 arrived at the car and a suited man spent around 30 minutes in the home.

The I'm A Celebrity star has not left the £2million house since arriving home at 2.40am after spending ten hours in police custody. 

Witnesses described McPartlin as being 'furious' when he got out of the car and he was seen shouting at his mother, Christine. 

The incident has sparked a number of fans to call for him to be axed for this weekend's Ant & Dec's Saturday Night Takeaway. 

The crash is the latest in what has been a troublesome year for the telly favourite, after he went to rehab for his painkiller addiction and the breakup of his marriage to Lisa Armstrong.
