Help! Witnesses to an assault that happened in front of Faces Nightclub Saturday night / Sunday morning at 1:15am

Actually, I think there is just too much here. Let me try and clean this up a little...

This is a long shot, I know. My friend was assaulted by 4 security guards outside of Faces Nightclub early Sunday morning at 1:15 am Oct 18th (yesterday). Tldr: He received trauma to his head and lacerations to several parts of his body. He was not drinking. He was out celebrating his girlfriends birthday as the designated driver and was forcefully removed from the bar by the security guards after asking for tap water to give to another patron of the club who was severely intoxicated and blacking out. Story: He had been drinking tap water all night being served by various bartenders throughout the club. This bartender for whatever reason wanted to charge him for it. He was confused and asked several times to please have tap water even informing the bartender it was for another patron who was blacking out. The bartender got annoyed and called security who forcefully dragged him from the bar then attacked him outside unprovoked. This guy is incredibly passive. I don't believe he's ever been in a physical altercation in his life let alone the type to go up against 4 bouncers at a bar. He's not a big guy. Unfortunately we didn't see any of this transpire which is why we need witnesses. We didn't find out what had happen till the following day 16 hours later when he was released for jail, his girlfriend was in hysterics for over 8 hours when there was no word from him the entire night. The police never took a report. They never read him his rights, they didn't even tell him why he was being detained. The officers at the jail never gave him any paperwork when he left the station only asking him to sign some documents saying he wasn't mistreated while in jail. When he asked why he was detained one of the jail clerks told him "probably because you were drunk in public" but he never had a drink that night. He never received a blood test or breathalyzer either. If you know anyone who may have been there that night I ask you to please reach out. If you've experienced anything similar or know anything that might help please send me a message.
