A gunman robbed a service station on Elmwood Avenue, near Amherst Street, over the weekend, Buffalo police said.

The man walked into Joe’s Service Center at 1602 Elmwood at 11:45 p.m. Saturday, pulled out a gun and demanded all the cash in the register, according to police reports.

The gunman’s face was covered by a hood.

He fled with an undetermined amount of money and ran west on Amherst Street, where an employee said he thought he saw the gunman get into a dark four-door sedan.
