Things took a violent turn at the Low Low Car Show in San Antonio this past Sunday (September 26) when Paul Wall got into an altercation with a fan during his performing.

The Houston native was on stage with his former Swishahouse label mate Slim Thug when a fan near the front of the crowd gave him the middle finger, according to reports from TMZ. The two then exchanged words, leading to Wall swinging at the concertgoer with his microphone several times. Security then stepped in and reportedly kicked the fan out of the venue. [Watch below]

The incident came in the midst of Slim Thug leading the crowd in an “R.I.P. P-I-M-P” chant in memory of the late Pimp C.
