Ann Arbor police officers told a man to move along after they found him sleeping naked on the concrete planters in front of the Federal Building in downtown Thursday afternoon.

Ann Arbor police Sgt. Mike Scherba said police responded at 1:52 p.m. to the building in the 200 block of East Liberty Street for a report of a man sleeping with his pants around his ankles.

Bystanders in the area were taking photos of the man sleeping in front of the federal building as they walked on East Liberty Street. Some passersby were walking directly in front of the man.

While a lot of strange things tend to happen in downtown Ann Arbor, people sleeping in the nude is rarely one of them, Scherba said.

“It’s fairly unusual,” he said.

Officers who responded to the scene had the man get dressed — his clothes were on the concrete planter nearby — and told him to leave the area. The man was not arrested.

Scherba said police were still in the area as of 2:30 p.m.

No further information was available.
