Detectives in Northern Ireland investigating the murder of prison officer David Black have issued a fresh appeal for information on the first anniversary of his death.
Mr Black, a 52-year-old father of two, was shot while driving to work in Maghaberry Prison on the morning of 1 November 2012.
The PSNI is making a specific appeal to people in Lurgan and Cookstown.
Detective Chief Inspector Richard Harkness, the officer leading the investigation into Mr Black's death, said he was asking people in those communities to think again about what they know and what they saw last year, and provide the information which can bring the killers before the courts.
To date PSNI Serious Crime Branch detectives have made seven arrests in connection with the investigation.
Yesterday, detectives conducted more house-to-house inquiries in Cookstown, and last week a search was carried out in the Cranagh Bridge area of Lurgan.
Two men, one in Northern Ireland and one in the Republic, currently face charges linked to the purchase and movement of the Toyota Camry vehicle believed to have been involved in the shooting.
