An Arlington man accused of robbing senior citizens while impersonating a police officer has been arrested, police said.

Rudolph Victor Curtis, 59, was charged with robbery, malicious wounding and impersonating a law enforcement officer, according to Fairfax County police.

Curtis on Wednesday approached a 93-year-old man in the 5700 block of Leesburg Pike and identified himself as a police officer and flashed some sort of credentials, police said. Curtis asked for the man's driver's license, struck him several times and took his wallet. The victim sustained minor injuries.

Detectives have linked the case to two impersonation incidents that occurred in June and July. The elderly victims in those cases had cash stolen but were not injured, police said. The charges against Curtis pertain only to Wednesday's attack. - Naomi Jagoda
