"It's quite an experience to have a pistol pointed in your face," said Barry, who is now a city council member, reports The Washington Post. A police spokesman said the department is investigating the complaint.
Barry told a local television station he gave the youths left after he gave them a couple of dollars. But they returned and pointed a gun to his head and took his wallet, which contained cash and credit cards, Barry said.
Barry served four terms as mayor and was elected to the city council in 2004.
