A 23-year-old woman is receiving medical treatment after she was raped outside the Batley Frontier nightclub in the early hours of Saturday.

Police have taped off the scene of the incident in Bradford Road, Batley, and are making enquiries.

Detective Inspector Andy Leonard of Kirklees CID said: "Police are investigating a serious sexual offence involving a 23-year-old female who is currently receiving medical treatment.

"The incident occurred at 5am and was reported to us at 6.10am."

Anyone who has any knowledge of what is alleged to have taken place should phone Kirklees CID on 01484 436680 .

The incident took place on Mad Friday, the last Friday before Christmas, when traditionally large amounts of alcohol are consumed.

Earlier this week Supt Paul Jeffrey had warned revellers in the Examiner to take great care over sexual liaisons saying : "alcohol is not a substitute for consent."

Batley Frontier is one of West Yorkshire's best-known clubs.
