THE gang that shot and killed Garda Adrian Donohoe during a robbery fled with just €4,000, Garda sources revealed today.
Detective Garda Donohoe, a father-of-two, was blasted in the head seconds after he stepped out of his car to confront raiders at Lordship Credit Union in a rural part of Co Louth on Friday night.
The gunman opened fire without warning. The 41-year-old Garda officer did not have time to draw his police issue weapon.
A cordon extending for several miles has been set up around the area.
Yesterday Ireland's most senior police officer Garda Commissioner Martin Callinan said no resources would be spared in bringing the killers to justice.
Up to 100 investigators from the Garda Special Detective Unit and the National Bureau of Criminal Investigation are involved. The Police Service of Northern Ireland have also offered assistance.
Detectives in Dundalk believe a criminal gang rather than dissident republicans were responsible. However, they said they were not ruling anything out.
Commissioner Callinan said: "There are up to four people involved in the actual raid. How many were involved beyond that will remain to be seen. We will put all our energy into finding out precisely who was behind this robbery.
"It is too early to speculate whether there was a subversive element to this or whether they are ordinary criminals."
This morning Detective Garda Donohoe was remembered during prayers at church services across the country.
His murder is the first of a serving Garda officer for 17 years and has sparked revulsion among the tight-knit police fraternity, political leaders and the wider community.
Cardinal Brady, leader of the Catholic Church in Ireland said people had been shocked and horrified.
