Three men assaulted another man on the dance floor at Los Imperios in West Hartford and police are asking anyone with information about the attack to come forward.
Police said security from the bar called police at 12:02 a.m. Friday and said a man had been assaulted and was unconscious in the bar area.
Officers who responded found a man without a shirt bleeding from the head. He came to and West Hartford Fire Department Medics treated him, but he refused further treatment.
The victim was uncooperative, but a witness told police three men attacked the man on the dance floor.
Security staff did not see the assault and did not detain anyone, police said.
One attacker might have had dreadlocks and was wearing a dark red zip-up jacket. Another wore a dark hoodie, police said.
Police ask anyone with information about the assault or who has video or photos to call Detective Robert Magao in the special investigations division at 860-570-8841.
Police said they also received several complaints from neighbors about patrons leaving and motorcycles racing up and down the street.
In addition to the two officers assigned to be outside of the business, four additional police cruisers and a supervisor were sent into the area.
In July, police revoked Los Imperios entertainment license after a series of violations and suspensions.
