The owner of the convenience store where Alton Sterling was killed last week by cops alleges in a lawsuit that police stole surveillance video from his shop, confiscated his cell phone, and locked him inside a car for the next four hours.

Abdullah Muhlafi, proprietor of the Triple S Mart, saw police confront and kill Sterling who was selling CDs with his permission in the front parking lot last Tuesday night. Muhlafi recorded part of the incident in footage he gave The Daily Beast last week that shows Sterling did not have a weapon in his hand when Officer Howie Lake shouted "gun!" and Officer Blane Salamoni fired six shots into his chest.

 Muhlafi claims in a lawsuit filed Monday in Baton Rouge district court that after Salamoni killed Sterling, he immediately ordered two responding officers to confiscate the "entire store security system" and detain him.
