Kiefer Sutherland has admitted that he mistakenly destroyed the only prototype of a Jack Bauer doll.

The actor was sent a hand-sculpted wooden model of the doll - based on his character in 24 - to gain his approval.

"Me and my friend took him out for a couple of drinks and, well, we lit him on fire," Sutherland confessed to Virgin's Hotline magazine. "We did a little action sequence, taking pictures of him with his gun going up in flames. The next day someone called and said 'You really need to send us that doll. That's the only one, it's hand-carved and we need to use that to make the mould!'"

Sutherland initially denied having anything to do with the doll's demise, but added: "I did [fess up] a little while ago."
