THE boss of a murdered policewoman has called on the people of Burnley to help him bring to justice her killer.

Chief constable Colin Cramphorn appealed for Burnley folk to help convict those responsible for the shooting of PC Sharon Beshenivsky.

His plea came as community leaders in the town said people must have information about one of those wanted for questioning, who was born in the borough.

The 38-year-old policewoman, a mother of five, died on her youngster daughter Lydia's fourth birthday on November 18 when she was blasted in the chest when attending an armed robbery in Bradford.

Her colleague PC Teresa Milburn, 37, was shot in the shoulder.

Burnley-born Muzzaker Imtiaz Shah, 24, is wanted in connection with the killing. He and Mustaf Jama, 25, are still at large.

Mr Cramphorn, chief constable of West Yorkshire police, said in his 30 years service he had buried 14 colleagues.

He said: "That is far too many. I don't want to bury another colleague and that is a pretty strong motivation to keep on searching.

"The best thing we can do for Sharon is to run a fully professional and committed investigation and pursue that to a successful conclusion."

Danehouse with Stoneyholme councillor Rafique Malik said if people were concerned about contacting the police they could ring Crimestoppers anonymously or himself and he would pass on the information in confidence.

He added: "I ask the people to come forward and tell the police anything they know about him or his family. If people are hesitant to go to the police I would urge them to contact me directly and I will pass on the information to the police.

"Its important the police should be accorded maximum support in tracing these people.

"I appeal to the people of Burnley and I am sure somebody must know something about him.

"They might not be responsible for what happened and it could be the police will clear them and get other vital information which will convict the culprits."

Fellow ward councillor Manzoor Hussain added: "Everybody should co-operate with the police and if anybody knows anything they should contact the police."

Detectives said Shah, whose street name was 'Pesci' or 'P' was born in Burnley but had lived in London for four years.

All ports, airports and key railway stations have been put on full alert and thousands of posters have been distributed to warn the public to look out for Britain's most wanted.

CCTV footage of the suspected getaway car, a silver Toyota Rav4, registration WP05 YTT has also been made public.

PC Beshenivsky joined the force in February after working as a police community support officer for nearly two years.

Her husband Paul Beshenivsky, said: "Sharon was my rock.

"She was loved by everyone who met her and my family's loss is felt by so many.

"The people who did this to Sharon and Teresa and to our families are cowards. They took away my wife, but they also took away a wonderful mum and the world is a darker place without her."

PC Beshenivsky's mother, Jenny Jagger recently described the last time the pair saw each other when they planned Lydia's birthday.

She said: "We spent a lovely day with Sharon, two days before she died."

"We had a chatty afternoon with her, sitting in the kitchen talking about Lydia's birthday."
