A man and woman were victims of a "strong-arm" robbery Saturday night in the parking lot at Chase Bank, 1401 Post Road.

The man was reportedly talking to the woman, who was sitting in the passenger seat of her car, when another man and woman approached about 7:30 p.m. and asked them for money, police said. When they refused, the woman in the car was struck in the face -- she was unsure by whom -- and her purse was stolen. Her face was bloodied by the attack, and was later treated in Norwalk Hospital. The male victim told police he was struck by the male suspect and knocked to the ground. Police said he suffered a laceration on the side of his face, but did not have any property taken

The male and female suspects ran south on Old Post Road toward Oldfield Road, police said. A K-9 unit was dispatched to help track the suspects, but the scent was lost on Old Post Road, at which point police said the pair probably fled by car.

Police said the victims described the suspects appeared to be light-skinned and either black or Hispanic. The female was wearing black-rimmed glasses, had long fake fingernails, and light-colored hair. The male suspect had long, curly hair and tattoos on his arms. Police said the victims believed both suspects to be between 18 and 20 years old.

The incident, police said, is under investigation.
