Two female yobs broke a teenage girl's teeth after they pushed her to the floor and punched her in the face.
It followed an argument between two groups of drinkers in the Civil Engineer pub in Ruislip Road, Northolt.
The 18-year-old was attacked at about 1.15am on Saturday (July 18). Both thugs are white and about 5ft 6ins. The first is about 20, skinny with brown hair and a was wearing a beige top.
The second is about 18, had bleached blonde hair and was wearing black sandals and top. She has a cockney accent. It is thought they both suffered injuries to their faces in the struggle.
