Officers received a call about a disturbance at Don Pedro, a bar, lounge and live music venue, in East Williamsburg at around 1:50 a.m. Sunday morning, authorities said.

Two men were arguing outside the bar near Boerum and McKibbin Streets, when one of the men pulled out a gun during the dispute. The other man followed suit and also pulled out a firearm. As one of the men turned to run, he heard gunshots and was struck by a bullet, police said.

A 20-year-old man, was shot in the left foot and in the ankle and was taken to Bellevue Hospital along with a 25-year-old woman, who was struck in the left thigh. Authorities say they are in stable condition.

Police said the second shooter hasn't been arrested.
