A 20-year-old Ypsilanti man said he was ordered to strip and was robbed at gunpoint late Friday by a man with a gun in one hand and bottle of alcohol in the other, city police said.

The robbery occurred in the 700 block of West Clark Street at about 11:10 p.m., a police news release said.

The 20-year-old told police he was with a friend when the stranger took them into a laundry room and told them to take their clothes off, the release said.

A cell phone and wallet were taken, the release said.

The man's friend ran and has not yet been interviewed, reports said. The 20-year-old went home and called his parents, who advised him to call police, reports said.

A detailed description of the robber was not available.

The investigation is continuing.
