The mother of a Catholic PSNI officer murdered by dissident republicans has said that young Catholics should not be put off joining the police because of his killing.

As the first anniversary of Constable Ronan Kerr's murder approaches, his mother Nuala said her son’s killers need to be caught, and she said there were people in the community who could help her family get justice.

Constable Kerr, 25, was killed by a booby trap bomb which exploded under his car in Omagh, Co Tyrone.

A member of the GAA, Constable Kerr was one of the Catholics recruited by the police to redress the religious imbalance of the old RUC.

His funeral saw unprecedented scenes of cross-community support, with members of the PSNI and the GAA standing side by side to carry the coffin.

Unionist politicians also attended his requiem mass.

To mark the first anniversary of the murder, Nuala Kerr said Catholics should continue to join the police, as she felt it was the only way forward. She said the dissident republicans who killed her son failed in their objective, achieved absolutely nothing, and should stop what they are doing.

As the hunt for the killers coninues, the PSNI have appealed for more support from the community.

A £50,000 reward from the charity Crimestoppers is still on offer.
