So a photographer is claiming Chris Brown sucker punched him the face. 

Apparently, Chris showed up to Aja Channelside in Tampa early Monday morning, around 1:30 am and his crew told their in house photogographer who had been snapping flicks of the card his shift was over.

A little while later, the photographer was taking pictures of the crowd from behind Chris as he was standing in the DJ booth and that Chris turned around and punched him in the face. 

By the time cops showed up, Chris had already dipped but they are investigating him for battery.
