THE FA has launched a swift investigation into the crowd trouble which marred Wolves’ FA Cup victory over fierce Black Country rivals West Brom today.

Play at the Hawthorns was suspended for over half an hour due to disorder in the stands and fans spilling onto the pitch.

West Midlands Police said two people were arrested after the disturbance and another was arrested prior to the match for possession of an offensive weapon, while a man was taken to hospital with head injuries.
