THE husband of murdered Bradford Pc Sharon Beshenivsky today told how he broke the news to his youngest children.

Paul Beshenivsky said he agonised for a week over how to tell them their mother had been killed.

Paul, seven, and Lydia, four, had been staying with friends since the murder last Friday - which was Lydia's birthday.

Mr Beshenivsky said that on entering the family's house Lydia saw hundreds of condolence cards.

She asked where her mother was and added: "There are so many cards. There must have been a lot of birthdays."

Mr Beshenivsky said he told the children their mother had gone to Heaven and "was keeping an eye on them".

Meanwhile, police are still hunting the three men named as suspects.

Police circulated pictures of Burnley-born Muzzaker Imtiaz Shah, 24, and Somali brothers Mustaf Jama, 25, and Yusuf Jama, 19, yesterday, a week after the 38-year-old officer was shot.

Shah was born in Burnley, but is believed to have lived in the London area for the last four years. The Jama brothers have been living in the capital's North Kensington area.

Pc Beshenivsky was gunned down as she and a colleague, Pc Teresa Milburn, 37 - who was shot in the shoulder - investigated a robbery at a travel agents in Morley Street.

Yesterday, Detective Superintendent Andy Brennan appealed for the public's help in finding the men.

After the shootings three men ran to a silver Toyota Rav 4, WP05 YTT, in nearby Howard Street.

Police have examined hours of CCTV film and had a number of sightings of the vehicle last Friday.

These included a sighting in Morley Street at 3.02pm, moments before the shootings. At 3.41pm it was seen on Manchester Road, going out of the city centre in the general direction of the motorway network.

Det Supt Brennan added: "We are appealing for any information about the vehicle and its occupants."

He said there was no indication that any of the men had left the country. It was possible they were still in the London area.

He said: "I am appealing for any information. Please look carefully at the photos. Have you seen these men? Do you know where they are?"

Asked what advice he would give to people who might come across them, he said: "That advice is very short and very simple. Please contact the police as a matter of urgency."

Det Supt Brennan said all three were in Britain legally and known to police, but he gave no further details.

He would not say what weapon was used to shoot Pc Beshenivsky.

Police have not recovered any weapons.

He said the three men had no known connections with Bradford, adding: "I can only assume that it was a random robbery."

Earlier this week six people were arrested in London and brought to West Yorkshire. Five men were released on bail, pending inquiries. A woman of 18 was freed without any charge.

Meanwhile, Bradford's Lord Mayor, Clr Valerie Binney, yesterday told people who gathered to remember Pc Beshenivsky that her sacrifice would never be forgotten.

More than 300 people braved icy temperatures at a short memorial service, followed by a two-minute silence, in Centenary Square.

Senior police officers, led by West Yorkshire Chief Constable Colin Cramphorn, other civic dignitaries, firefighters and members of the public gathered for the ceremony.

None of Pc Beshenivsky's family attended the service.
