GARDAI are carrying out a fresh review of their files to establish how killer Jerry McGrath was granted bail on other charges before he murdered Sylvia Roche Kelly.
It was prompted by allegations of garda misconduct and incompetence by "whistleblower" Sergeant Maurice McCabe. It emerged last night that Sgt McCabe had made the allegations and that they were investigated by the garda authorities.
This led to an investigation file being sent to the Director of Public Prosecutions, which decided against a criminal prosecution.
But a separate internal garda probe found that there had been breaches of process and procedures when they examined the complaints lodged by Sgt McCabe.
These resulted in disciplinary action being taken against several members of the force, and some of them were transferred to other stations.
Gardai are now trying to establish if investigating gardai objected to McGrath's bail after he was arrested for attacking a woman taxi driver in Cavan and if the application was made in the district court or if his lawyers went to the High Court.
They are also trying to find out if the investigating gardai in Co Tipperary had been aware of this incident.
