London, Jan 29 : A stuntman who doubled for Daniel Radcliffe in the Harry Potter series has been injured in a horrible explosion on the set of the film.

The 25-year-old, who has been standing in as Radcliffe's stunt double in all the Harry Potter films, was rehearsing a flying sequence by using a harness, when he was sent flying by the blast.

Though he was still conscious after slamming to the ground, he told his horrified colleagues: "I can't feel my legs," the Mirror quoted him as saying.

"The stunt double was badly hurt. He was rehearsing a flying scene, which involved an explosion, and it seems to have gone badly wrong. The guy was rigged up to a harness for the scene and was flying through the air," a source said.

"It is thought he may have been caught by the explosion and hit the ground very hard.

"He told crew members who went to help him he couldn't feel anything from the waist down. Everyone is just hoping he makes a good recovery. It has come as a terrible shock," the source stated.

The accident happened at the world famous Leavesden studios near Watford, and paramedics took him immediately to the hospital amidst fears that he may have been paralysed.

"We can confirm a member of the Harry Potter production was injured in an accident. We are awaiting further news," a spokesman for the studio said.

"Out of respect for the family we are unable to comment further," he added.

The incident took place while the crew were doing pre-production work for the seventh series, `Harry Potter and the Deathly Hallows', which will be out in 2010. (ANI)
