The mother of a Leicester man shot dead at a music event has pleaded with his friends to help bring his killer to justice.
So far the friends of Sylvester Koroma, who were with him when he was shot outside a Birmingham nightclub, have refused to talk to police.
Now Eunice Koroma has appealed directly to them to give the family "closure".
