North Carolina’s governor has declared a state of emergency in the city of Charlotte, after violence erupted during a second night of protests over the police killing of a black man.
Keith Lamont Scott was shot dead by a black officer on Tuesday.
One protester remains in a critical condition after a “civilian on civilian” shooting, police said.
Nine protesters were also injured while police arrested 44 people, according to the police chief.
Charlotte-Mecklenburg Police Chief Kerr Putney said charges included looting, failure to disperse and assault.
Five officers also required medical care, including two for minor eye injuries, he added.
Mr Scott was the third black man killed by US police in a week. Such shootings have sparked nationwide protests.
