Mob Beating at 26th and Mission

Tonight in San Francisco around 2:00 a.m. as the 26 club on Mission Street was closing(intersection of 26 and mission) a mob fight broke out with about 15 - 20 Latinos guys who came out of club 26. Four of the security from the club tried to break up the fight, as I was driving by I called the police to intervene. I witnessed one of the men grabbing a orange and white construction piece and hitting the other man over the head. In addition there were several punches thrown and some wooden clubs used.
