Erie County sheriff’s deputies arrested two men for drunken driving during separate incidents Saturday morning.

A one-car rollover about 3:30 a.m. on Versailles Plank Road, near Snow Road, on the Cattaraugus Indian Reservation resulted in the arrest of the driver, Spencer G. Shipley, 42, of North Collins, sheriff’s officials said. A breat test showed Shipley’s blood-alcohol content at .15 percent, or almost twice the legal limit, officials said. He was treated at the scene for minor injuries.

About an hour later, Joseph S. Rebmann, 29, of Gowanda, was stopped on Route 39 in Collins for speeding and charged with DWI, sheriff’s officials said. His blood-alcohol content was .12 percent, the sheriff’s office said.
