Police have released CCTV footage to demonstrate that Michael Brown was a robbery suspect before he was shot dead by police.
The images appear to show Brown confronting a store employee.
Police said they have only released them after receiving "several freedom of information requests" from journalists.
Michael Brown had become a suspect in the theft of cigars from a store only minutes before he was shot dead by the police, reports claim.
But police said that the officer who shot him had no idea 18-year-old Brown was a robbery suspect and he simply wanted him to move from the road to the pavement.
