*Police are searching for witnesses after a woman sustained head injuries at a Wiz Khalifa concert in New Hampshire on April 8.

The unnamed female fan was found unconscious behind the Whittemore Center Arena in Durham, New Hampshire following the rapper’s performance there last Friday. She was taken to a local hospital to receive treatment for head injuries.

The woman is believed to have fallen off a wall during the rapper’s show. Cops are investigating the incident and are appealing for any potential witnesses to come forward.

Deputy Police Chief Paul Dean says, “At this time we don’t know what happened. We are looking for anyone who may have witnessed what happened or who has information to step forward. We are in the early stages of the investigation. Until we can speak to the victim we are not ruling out that a crime has taken place.”
