A 62-year-old man was robbed of his Oxycontin prescription at gunpoint in Ypsilanti Saturday, city police said.

The Battle Creek man told police he was in the 100 block of South Grove Street at 2:26 p.m. when a man took out a semi-automatic handgun. The robber ordered him to hand over his prescription, a police incident log said.

The robber then walked away.

Police have identified the man believed to be responsible and are looking for him, according to the log.
