WATCH: Trey Songz Altercation at Kansas City Chiefs Game

Trey Songz was arrested for trespassing, resisting arrest and for assaulting a police officer after a physical altercation during the Kansas City Chiefs NFL playoff game yesterday.

A witness claims the whole thing started when Trey was being heckled by some fans a few rows behind him and he asked them to chill out. The officer approached Trey, and without warning, went after him. The witness says Trey was totally caught off guard when the officer got physical, and started to defend himself.

You can hear fans throughout the video shout at the officer, telling him to get off of Trey until additional officers arrived. Fans were yelling for the officer to be arrested.

Once backup got there, they were able to separate Trey and the cop, and they put Trey in handcuffs.
