Actor Shia LaBeouf was due to return to the set of the Transformers sequel on Thursday, less than three weeks after he shattered his left wrist in a car crash.

The 22-year-old, who was out and about in Los Angeles on Wednesday, underwent extensive hand surgery following the wreck and is still wearing a brace on his wrist.

His fingernails remain black due to bruising and bleeding under skin.

The Indiana Jones star was arrested on a suspicion of drink-driving when his Ford pick-up truck collided with another vehicle at a junction in West Hollywood around 3am on 27 July.

LaBeouf was taken to Cedars-Sinai Medical Center after injuring his left hand, head and knee.

The star was attempting a left turn at the crossroads of La Brea Avenue and Fountain Avenue when he collided with an oncoming vehicle and flipped his car.

The contents of LaBeouf's car, including pizza boxes containing hot pizza, a brand new toilet seat in its box and a rucksack were thrown out of the car and strewn across the road.

Los Angeles County Sheriff's Sgt. Scott Wolf said: 'It was immediately apparent to officers responding on the scene that LaBeouf was intoxicated and he was subsequently placed under arrest.'

LaBeouf was booked for a misdemeanour charge of driving under the influence.

His female passenger and the driver of the other vehicle were not seriously injured in the smash.

However, police spokesman Steve Whitmore announced two days after the crash that LaBeouf 'was not at fault'.

'We have strong evidence that the other driver ran a red light,' he added.
