Darren Wilson, the police officer who shot dead unarmed black teenager Michael Brown has resigned from the Ferguson Police Department, his attorney said, according to Associated Press.
The news agency reported the decision, which comes nearly four months after the fatal confrontation with the black 18-year-old that fueled protests in the St. Louis suburb and across the nation.
The mayor of Ferguson, the St. Louis suburb torn apart by clashes over the shooting of unarmed black teenager Michael Brown, said the community must move on.
His remarks came after the resignation of officer Darren Wilson, who shot Mr Brown, announced his resignation.
Mayor James Knowles said he had not asked for Wilson's resignation, and even though the officer expressed an interest "in a future here," Mr Knowles said he wanted the city to turn a page.
"I think it is best that we continue to move on as a community," he said.
Armies of protesters took to the streets following the Ferguson shooting decision, in a sign of the monumental challenge now facing America.
The police officer who shot dead Michael Brown says he has a clear conscience over his actions.
