A number of calls were made to the inquiry team after a reconstruction of the last hours of the 17-year-old's life was shown on BBC Crimewatch.

Det Supt Geraint Jones said he still wanted to hear from people who knew what happened to the teenager.

Shafilea's body was found in Cumbria in 2004, six months after she vanished from her home in Warrington, Cheshire.

No-one has ever been charged in connection with her death.

Mr Jones, leading the investigation, was in the BBC studio on Wednesday night to make a direct appeal to anyone with information to come forward.

"We are delighted with the public response following the Crimewatch appeal," he said.

He also urged anyone who saw a white van parked in the area where Shafilea was found to contact his team.

"We've had several calls around vehicles at the scene – some very interesting ones – and we're following up on those," said Mr Jones.

Officers say they also received a promising number of calls offering information from both Cumbria and Cheshire.

The information is now being assessed by members of the investigation team, who will be following up lines of inquiry.

"We are delighted with the public response following the Crimewatch appeal, delighted with the number of calls," a force spokeswoman said.

Last month, South Cumbria Coroner Ian Smith said Shafilea, who had feared a forced marriage, was the victim of a "vile murder".

Shafilea's decomposed body was found by the River Kent at Sedgewick, near Kendal, in February 2004. In January, the coroner ruled Shafilea had been unlawfully killed.
