A millionaire is facing years behind bars for launching a 'Raging Bull' attack on a taxi driver after drinking £14,000 worth of vintage champagne.

Craig Pesch, 33, had been out for drinks at some of London's most exclusive bars before ordering a cab to pick him up at 4.20am outside the exclusive Maddox Club in Mayfair.

When 71-year-old driver Ratid Shilaka struggled to find Pesch's house on his satnav, the drunken businessman threw a 'merciless' volley of punches at the pensioner's face.

Shilaka was rushed to hospital and had to undergo surgery to rewire his jaw after Pesch fled the scene stained with his victim's blood.

The unprovoked beating was so violent it was likened to Robert De Niro's portrayal of ultra violent boxing middleweight Jake La Motta, Westminster Magistrates heard.

"Mr Shilaka was a punching bag for a Raging Bull,' said prosecutor Edward Aydin.

"Mr Pesch mercilessly punched the victim in a sustained attack with immense force.

"He was strapped into his seatbelt at the time and Mr Pesch was knocking him around like a rag doll."

The court heard the confusion over Pesch's new-build address was the only motive for the brutal assault that has forced Shilaka out of work and left him drinking liquid food through a straw.

Mr Aydin said: "He got into Mr Shilaka's taxi and told him he wanted to go to SW18. Mr Shilaka put the address into his satnav but it didn't show as a valid address.

"Mr Pesch then got out the car, opened the driver's door and began punching Mr Shilaka repeatedly."

Pesch told officers he had "fallen over" when he was found at 4.40am covered in blood under the statue of Ronald Reagan at the U.S. Embassy in Grosvenor Square, Mayfair.

He initially denied all knowledge of the attack, offering "no remorse, no guilt, no mea culpa", and later claimed he had been drunk.

"In all the witness statements there is no evidence of him being drunk, of him being unsteady, or his speech slurred, it's only him saying he was drunk and had drank £14,000 worth of alcohol," said Mr Aydin.

Shilaka was treated for facial lacerations that were "oozing blood" at St Mary's Hospital, and was later transferred to Northwick Park Hospital for surgery.

He has suffered from flashbacks since the attack and has been too fearful to return to work, losing out on £7,200 in wages.

Pesch admitted causing grievous bodily harm during the incident.
