OAKLAND -- Three employees of an East Oakland nail salon were pepper sprayed and one was pistol whipped during a robbery Monday afternoon, police said.

Five suspects are being sought, including three women who did the pepper spraying.

The three women pulled pepper spray and blasted a 58-year-old man in the eyes and took money and a cellphone from him before he was hit in the head by the gunman, police said.
