SKOWHEGAN — A Vietnam veteran fired shots inside a downtown tavern Wednesday night, causing the State Police Tactical Team to surround the area.

The man was identified as Dennis Gehrke, reportedly from Madison.

Witnesses said Gehrke walked into the Old Mill Pub on Water Street around 9:30 p.m. brandishing a shotgun. He reportedly fired several shots before letting everyone in the bar leave.

The tactical team still had the downtown area blocked off at midnight.

State police were unsure whether Gehrke was still in the bar or whether he managed to escaped out the back down to the Kennebec River.

Witnesses said Gehrke’s former girlfriend reportedly works at the bar.

No injuries were reported in the incident.
