The family of Detective Garda Adrian Donohoe have received a special medal in his honour.

The 41-year-old was shot dead during a robbery at a credit union in Co Louth on 25 January.

Minister for Justice Alan Shatter and Garda Commissioner Martin Callinan were at Dublin Castle this morning as Det Donohoe's widow Caroline and two children were presented with the remembrance medal.

It was awarded during the annual garda memorial service for the 87 officers who lost their lives in the service of the State.

Commissioner Callinan described the murder of Det Donohoe as a terrible event that was still very raw.

Mr Shatter said it was an unspeakable crime and life-changing for his family.

He said it was tragic that Det Donohoe's name was added to a roll of honour that continues to get longer.
