Detroit police have a person of interest in the case of a stolen rental truck packed with equipment for a vice presidential Labor Day campaign event.

According to police, investigators need help identifying this man.

The stolen U-Haul was recovered on Monday, said the Secret Service.

Agency spokesman Ed Donovan said the U-Haul truck that disappeared on Sunday from the Holiday Inn Express was discovered by police near Henry Ford Hospital.

Some of the contents had been recovered earlier in the day in an abandoned house and the rest appeared to be inside the truck, Donovan said.

Donovan would not describe the gear, but a law enforcement official who did not speak for attribution said there were no weapons inside the vehicle.

Vice President Joe Biden spoke at a downtown rally organized by the Michigan AFL-CIO.
