Detectives hunting for the killer of Bradford prostitute Rebecca Hall hope an appeal on national television will bring forward fresh information.

Officers leading the investigation into the murder of the 19-year-old will appear on the BBC's Crimewatch programme tonight to urge those with more information to come forward.

It is now more than two months since Becky was murdered and dumped in an alleyway behind the car park in Thornton Street, Bradford.

She died from severe head injuries and had sustained a vicious and brutal beating.

Her body was discovered on Thursday, April 26, but she had not been seen since she left her home in Lydford House, off Elizabeth Street, Little Horton in Bradford, at about 10pm on Friday, April 13.

Becky was a prostitute and it is thought she was heading to the Thornton Road area. Detectives are investigating the theory she was abducted and held somewhere before she was killed.

Detective Chief Superinten-dent Max McLean, heading the murder investigation, will app-ear on Crimewatch alongside Toni Johnston of the Bradford Streets and Lanes project which cares for young prostitutes.

To contact Crimewatch call 0500 600 600 or the police freephone hotline on 0800 318 001.

Prostitutes can also contact the Streets and Lanes project with information if they do not wish to speak to the police.
