Hip hop artist Chris Brown is a "person of interest" in an investigation following his performance at the Pepsi Center on Sunday night.

A woman claims she was "forcibly thrown off" of Brown's tour bus after refusing to give up her cell phone - violating Brown's "no cell phone" policy. According to TMZ, the incident happened outside a strip club on Umatilla Street.

The unidentified woman filed a report of third-degree assault, claiming her cell phone was damaged.

Brown was filming a music video with fellow artists French Montana and Fetty Wap at Platinum 84 Gentleman's Club the same night.

TMZ says there is surveillance video of the incident and police want to talk to Brown.
