Danny McCullough III, 38, was being escorted out of Lager House early Sunday morning when the incident took place, the New Haven Register reported.
Bouncers told police McCullough had been standing in the rear patio of the bar as it closed, and refused to finish his drink and leave. As McCullough argued with the bouncers, one of them crushed his drinking cup, and McCullough picked up a glass bottle as if to strike the man, police said.
McCullough, who lives in Washington D.C., then pointed his Glock 9mm weapon at the ground, police said. Two women reported hearing him say words to the effect of: “That’s right it’s a real gun,” police said.
D.C. police told NBC Washington that they're aware of the situation and that internal affairs is investigating.
McCullough, a member of the Metropolitan Police Department since 2003, was off duty at the time of the incident, D.C. police said.
McCullough faces charges of breach of peace, reckless endangerment and resisting arrest, the New Haven Register reported.
