Denver police spokesman Sonny Jackson said Monday that 34-year-old Faustino Ibarra is being held without bond while awaiting extradition to California after his arrest on Saturday.
In a jailhouse interview with KDVR-TV ( http://bit.ly/TpJirK), Ibarra claimed Allen adopted him years ago. Jackson said there is no evidence of any adoption.
Ibarra said Allen had left the door to his garage open along with the keys.
Police confirmed that the customized 1996 Chevrolet Impala SS belonged to the "Home Improvement" star but said it hadn't yet been reported stolen when it turned up in Denver.
Allen's publicist Marleah (mar-LEE-uh) Leslie said she wouldn't comment because it's a police matter.
