An enraged man chomped off a chunk of a bouncer’s finger when he was denied entry into a Queens bar that had closed for the night, police said Wednesday.

The 37-year-old worker was closing the doors to California Sports Bar on Roosevelt Avenue in Elmhurst shortly after 4 a.m. on Feb. 16, when the stranger approached and tried to get in.

When the bouncer told him the bar was closed, the man began squabbling with him — and then bit off his part of his left pinky fingertip, including the nail, police source said.

The suspect, whom police described as having a medium build, a goatee and dark hair. He ran off east on Roosevelt Avenue. He was also wearing “a black jacket with Japanese iconography inscribed throughout.”

His victim was taken to Bellevue Hospital Center, where doctors were able to reattached his finger.
