Hundreds of demonstrators took to the streets in North Carolina after police shot and killed a black man while they were looking for a different person.

More than 200 protesters had gathered in Charlotte after a black police officer shot dead Keith Lamont Scott, just one day after a white officer killed an unarmed black man in Oklahoma.

Police said in a statement that the 43-year-old got out of his car holding a firearm and posed an "imminent deadly threat".

Posts on social media reported that Mr Lamont Scott was unarmed and disabled.

Police said that a weapon had been recovered from Mr Lamont Scott, but did not comment on whether he was disabled or not.

The protest began to disperse late on Tuesday night after police fired tear gas on the crowd and an emergency unit was dispatched to remove officers.

Charlotte-Mecklenburg Police Department reported that 12 officers had been injured in the demonstration and that protesters had been destroying police vehicles.

Demonstrators at the scene, some carrying signs reading "Black Lives Matter", chanted "Hands up, don't shoot".

The officer who is said to have fired the fatal shot has been placed on administrative leave pending an investigation.

The shooting comes just a few months after the fatal shooting of two black men by police officers in Louisiana and Minnesota.
