‘Hunt for garda killers will be slow and difficult’

Garda Commissioner Martin Callinan has said nobody should underestimate “just how difficult” the hunt for Detective Garda Adrian Donohoe’s killers will be.

He said the investigation will be “quite slow and quite painstaking” and appealed to an outraged public to give detectives “some space” to carry out their inquiries.

Justice Minister Alan Shatter said the five-man gang involved in the murder in Co Louth were not “operating in a vacuum” and appealed to those with information to come forward.
