Nov. 4, 2009 (United Press International) -- A Denver man who claimed to have been attacked has confessed he stabbed himself to avoid having to work, police say.

Investigators said Aaron Siebers, 29, walked into his place of employment, a Blockbuster Video (NYSE:BBI) in Edgewater, Colo., at about 6:30 p.m. Monday with a deep stab wound to his lower leg and several superficial knife wounds, The Denver Post reported Wednesday.

Police became suspicious of the account after Siebers' description of his attackers changed from three skinheads to a trio of Hispanic males and a review of outdoor security camera footage from a nearby store, where he claimed the attack took place, did not show any violent incident. Siebers eventually confessed to police that he stabbed himself and made up the story to get out of work, the Post said.

Siebers, who received several stitches in his leg, was arrested and charged with false reporting and obstructing a police officer. He was booked into the Jefferson County Jail.
