hollywood nightclub shooting*Saturday night / Sunday morning in Hollywood a man was shot and killed in the midst of an all out brawl which was caught on tape by a TMZ photographer.

Police say the incident started inside the Empire nightclub where several fights broke out between some women … before it moved outside.

In the video (below), you can see women throwing punches, pulling hair, slapping etc.

Within minutes the violence escalated into all out mayhem … dozens more joined in — men and women.

Suddenly … a man in grey sweatshirt pulls a gun … aims at a man — and two shots are clearly heard.

Moments later, you see a man lying dead in the middle of the street — and appears the victim was the intended target.

Another man was also shot during the brawl.  He’s in stable condition.

LAPD is investigating.
