An off-duty D.C. police officer shot and wounded a man who tried to rob her early Tuesday in Southeast Washington, authorities said.

Inspector George Dixon, head of the Internal Affairs Division, said the officer was on personal business and wearing civilian clothes when she was accosted near her car about 6:50 a.m. in the 1600 block of 18th Street.

The man indicated that he had a weapon in his waistband and said he was going to rob her, police said, and the officer took out her department-issue service weapon and fired one shot into the man’s stomach.

The shooting occurred just off Minnesota Avenue near the Anacostia Freeway, an area of mostly apartments.

Dixon, whose division investigates police-involved shootings, declined to say whether police recovered a weapon from the man, who was not identified. He was being treated at a hospital for injuries police said did not appear to be life-threatening.

Dixon said charges against him are pending.

The officer, whom officials declined to name, has been placed on routine administrative leave pending the outcome of the investigation. She joined the force in January 2012, Dixon said.

The shooting was the eighth by a D.C. police officer this year. In three of them, suspects were killed, including the man who fatally shot 12 people at the Washington Navy Yard last month.

D.C. police were not involved in last week’s shooting of woman who led authorities on a chase from the White House to the Capitol. She was fatally shot by Capitol Police and agents from the Secret Service.
