Police have renewed pleas for help to trace a man wanted in connection with the murder of Keighley policewoman Sharon Beshenivsky.

The appeal was made this week on the fourth anniversary of the shooting of PC Beshenivsky outside a Bradford travel agency.

Police believe that 50-year-old Piran Ditta Khan, who has been hunted since the murder, may be in Pakistan.

And through Crimestop-pers they have issued a wanted poster and an offer of a £20,000 reward.

PC Beshenivsky — from Hainworth — was shot dead as she and a colleague attended a report of a robbery at Universal Travel Agents, in Morley Street, on November 18, 2005.

Six people have already been convicted for their part in the robbery and murder, one of them recently extradited from Somalia.

Det Supt Andy Brennan, who has led the inquiry throughout, said: “I am as committed now as I was in November 2005 to see this inquiry through to a conclusion. It is extremely important we trace Piran Ditta Khan and place him before the courts in Great Britain.

“I am appealing directly to people in Pakistan — if you know, or suspect you know, where Piran Ditta Khan might be, please tell us.” Crimestoppers can be contacted on 0800 555111, or call 0044188 373 1336 from abroad.
