Dallas police have released this image of a man armed with an assault rifle walking through a group of protesters and they say he is a person of interest in the fatal shooting of at least 4 officers at the Black Lives Matter protest in Dallas, Texas, on Thursday.

The man was dressed in a camouflage shirt and black shorts, and shockingly walked openly with his weapon without anyone pointing out the rifle to police officers.

One witness told CNN he was from out of state, and thought that was just common in Texas.

Two snipers are believed to have targeted the Dallas cops shot to death from an 'elevated position' in the middle of a protest against the deaths of Alton Sterling and Philando Castile. A manhunt is now
underway for the two suspects, one of whom is this man.

The force tweeted: "This is one of our suspects. Please help us find him!"

Dallas PD want to talk to the man about the shootings which killed 4 officers and wounded 7 others during an ambush.

Racial tensions are on the verge of boiling over in the US following the deaths of Alton Sterling and Philando Castile.
