DETROIT (AP) — Detroit police have released photos of a male "person of interest" in the theft of a Secret Service rental truck carrying equipment related to Vice President Joe Biden's Labor Day visit to Detroit.

Agency spokesman Ed Donovan tells The Detroit News that the U-Haul truck stolen early Sunday outside the Westin Book Cadillac hotel was found Monday in a parking lot about three miles away.

Donovan had said the truck had no weapons on board. He declined to say whether any of the equipment was stolen.

Police spokeswoman Sgt. Eren Stephens tells The Associated Press in an email that investigators hope people will see the photos and help identify the man.

Biden addressed a union rally Monday to mark Labor Day. The rally was near the hotel.
