Police have named Darren Wilson as the officer who fatally shot unarmed teenager Michael Brown in Missouri.
Ferguson Police Chief Thomas Jackson made the announcement at a press conference.
Jackson also released documents that claim the teen was killed after a robbery in which he was suspected of stealing a $48.99 (£29) box of cigars.
Ferguson police had previously withheld the name of the officer involved citing security concerns.
The shooting of the black 18 year old has led to racial tensions and protests in the St. Louis suburb of Ferguson where Brown was killed.
