Chris Brown is at the centre of a police investigation after a woman claimed she was forcibly thrown off the singer's tour bus during a music video shoot in Denver, Colorado on Monday night (14Sep15).

Cops in Denver have launched a probe after a female filed a report alleging she was assaulted when she refused to hand over her cell phone while Brown was shooting a new promo with rappers French Montana and Fetty Wap at a strip club.

She also reportedly claims her phone was broken in the bust-up.
