A Garda who was shot dead last night has been described by Senior officers as dedicated, diligent and hugely popular.

Detective Garda Adrian Donohoe, a father of two aged in his 40s, was killed last night as he tried to stop raiders escaping with cash from a Credit Union in Co Louth.

Several shots were fired during the attack at the Lordship Credit Union, on the Cooley Road in Bellurgan.

It is understood that the officer was shot without warning and had not drawn his weapon.

Gardai say up to four people were involved in the actual raid who were spotted leaving the scene in a dark coloured car.
