Former TV child star Gary Coleman has died at the age of 42, after suffering a brain haemorrhage earlier in the week.

The actor had been taken to hospital on Wednesday after a fall at his home in Santaquin in the US state of Utah.

Although reports say he was conscious when he arrived at hospital, he slipped into unconsciousness on Thursday and was placed on a life support machine.

Coleman was best known for the hit US sitcom Diff’rent Strokes, which ran from 1978 to 1986.

His character, Arnold Jackson, coined the classic catchphrase ‘What you talking ’bout, Willis?’

However he struggled with his health throughout his life, and was troubled with financial woes after the show was cancelled.

Coleman suffered from the kidney condition nephritis and had two failed transplants as a child. As a result of his illness he never grew taller than 4ft 8in.

He sued his parents for mismanagement in 1993 and won a multi-million dollar settlement, only to file for bankruptcy six years later.

The star had also had a number of run-ins with the law for disorderly conduct and reckless driving.

In recent years however he had settled down in Utah when he went there to star in the movie Church Ball, a comedy based on basketball leagues formed by the members of the Church of Jesus Christ of Latter Day Saints.

He met his wife, Shannon Price, on the film set and married her in 2007.
