The boyfriend of The Hills star Stephanie Pratt was arrested in New York after he drove his Ferrari 458 Spider over a policeman's foot.
Julien Chabbott, 28, was filmed getting into his car as a policeman was issuing him a ticket outside the Mercer Hotel in Manhattan's SoHo district on Saturday.
But when the policeman stood in front of the car to stop him driving away, he pulled forward slightly.
What happened next was caught on camera by a passer-by, Damian Mory, who posted the footage online.
Chabbott continues to creep forward before the policeman slams his hand into the window.
"What the f--- man?" the policeman screams.
"You run down my f---ing foot."
The policeman throws open the car door and pulls him out as other officers help to pin him to the ground.
His girlfriend, Pratt, can be seen watching from the pavement as he is arrested.
Chabbott was charged with assault, vehicular assault and obstructing governmental administration, the New York Post reports.
Mr Mory wrote on his YouTube account that the car was parked legally in the hotel's valet zone and couldn't understand why Chabbott was being issued the ticket.
"Pretty crazy situation, I was definitely at the right place at the right time," he wrote.
