Protests persist over latest racially-motivated Louisiana shooting

Mourners, friends and relatives of Alton Sterling met once again outside the shop in Baton Rouge where he was killed early on Tuesday morning.

About 200 people protested on Tuesday night and on Wednesday there was unrest in Philadelphia where about 75 people blocked a busy road as they protested Sterling’s killing.

Sterling was the latest in a long series of African Americans who died at the hands of the police, who seemingly used accessive force.

Videos posted online show Sterling being held down and then shot several times, although some shots are heard when the camera moves away from the confrontation.

Seconds later, one of the officers is seen removing an object from the man's trousers as he lies on the ground with blood on his chest.

At the protest, some chanted "Black lives matter" and called for justice.

Police have said Sterling was found to be armed. Officers were initially called because of a 911 report of a man brandishing a gun.

The latest video provided by shop owner Abdullah Muflahi, who said it proves the man was no threat to the officers when he was shot.

Officers Blane Salamoni and Howie Lake II who carried out the shooting were put on administrative leave, the BBC reports.

The US Justice Department has reportedly launched a civil rights investigation and Louisiana Governor John Bel Edwards has appealed for calm.

The high profile cases of police officers using accessive violence against people of colour has recently ignited a national debate about the lethal use of force.
