Machete attack arrest: A third person has been arrested in last month's machete attack on a 16-year-old Alexandria area youth, Fairfax County police said yesterday. The man is believed to be a member of the Mara Salvatrucha street gang.

Jose Cruz, 19, of the 4900 block of Manitoba Drive in Annandale was arrested Thursday about 8 p.m. in the Orleans Village townhouse complex off Little River Turnpike. He was charged with aggravated malicious wounding and participating in gang activity. Hayner R. Flores, 18, and a 17-year-old whose name was not released face the same charges in the May 10 attack on a reputed rival gang member. Four of his fingers were severed and he suffered deep cuts to his head and back. Flores and the 17-year-old also are members of Mara Salvatrucha, police said.

Police impersonator: Arlington County detectives are investigating two robberies in which a man impersonated a police or security officer and took cash from his victims.

On June 11, police said, a man in plain clothes approached a woman in the 1300 block of South 28th Street, flashed an ID and asked for the victim's wallet. He returned it, but without the cash.

In a second incident June 13, a man approached two men in the 4200 block of Columbia Pike and flashed an ID and asked for the victims' wallets, police said, then proceeded to take their cash.

Police said they believe the same man is responsible in the robberies. Police are asking anyone with information to call 703-228-4169 or Crime Solvers at 800-673-2777.
