Washington : Police shot down a young man after he opened fire at them in the US state of Missouri during protests to mark the first death anniversary of black teenager Michael Brown who was killed by a white police officer last year, media reports said on Monday.
St. Louis county Police Chief Jon Belmar said the man was in a critical and unstable condition, and undergoing surgery at a hospital in Ferguson, USA Today reported.
A St. Louis county officer was involved in a shooting after coming under heavy gunfire, said St. Louis County police on its official Twitter account.
Earlier, Belmar said the shooting occurred after undercover detectives monitored an individual in the crowd who they believed was armed and had three or four possible armed acquaintances.
A shootout also broke out between two groups and the suspect ran away. He was then spotted by police detectives in an unmarked vehicle, which began driving towards them with the emergency lights activated. The police detectives fired at the vehicle, hitting it a number of times.
