Video footage has emerged showing Darren Wilson – the police officer who shot and killed Michael Brown, an unarmed Black 18-year-old in Ferguson, Missouri – threatening and arresting a resident who refused to stop filming him with a cellphone.

Wilson is seen standing near his Ferguson police SUV and warning Mike Arman: “If you wanna take a picture of me one more time, I’m gonna lock your ass up.” Arman, who had requested Wilson’s name, replies: “Sir, I’m not taking a picture, I’m recording this incident sir.” The officer then walks to the porch of Arman’s home and apprehends him, after telling him that he does not have the right to film.

The 15-second clip was uploaded to YouTube on Friday but recorded in 2013, according to police documents.
