Star Trek actor William Shatner has raised $25,000 (GBP14,000) for a housing charity by selling his kidney stone to an online casino.

Gambling website are the lucky new owners of the 74-year-old's unique item of memorabilia.

Shatner says, "This takes organ donors to a new height, to a new low, maybe. How much is a piece of me worth?"

The actor passed the stone in August 2005, after he collapsed on the set of his US show Boston Legal.
