Police say a black teenager shot dead by an officer was suspected of robbing a store shortly before he was killed.
They released documents saying Michael Brown, 18, was believed to have stolen a £30 box of cigars from a convenience store in a "strong-arm" robbery in Ferguson, a predominantly black suburb of St Louis, Missouri.
Police Chief Thomas Jackson said the officer did not know he was a robbery suspect at the time of the shooting and stopped Mr Brown and a companion "because they were walking down the middle of the street blocking traffic".
The officer who shot Mr Brown, Darren Wilson, 28, had been a policeman for six years and had no complaints filed against him, Mr Jackson said.
