The incident took place at the Elks Lodge at 600 Washington Street just before midnight.
Police say a 70-year-old male bartender and a 66-year-old female member of the lodge were closing up for the night when the armed male suspect entered.

During the struggle, police say, the 66-year-old female hit the suspect with a large bottle of alcohol.
Neither of the victims received injuries.
The suspect took over $1,000 before fleeing on foot to the rear of the lodge towards Clifton Avenue.
The suspect is described as a white male, 6' 1, heavy build, with dark curly hair. He was wearing a dark ? blue parka, a dark skull cap and had a blue and white scarf covering his head.
