A man in his early 20s has been arrested in relation to an investigation into the murder of convicted criminal Michael Devoy (42).
The man was arrested in the Dublin area this morning and is currently detained at Tallaght Garda Station.
Ballymun criminal 'Mad Mickey' Devoy was shot dead in a revenge attack in January.
Detectives believe he was shot dead as revenge for the attempted murder of gang boss Greg Lynch.
Devoy was shot three times in the head before his body was dumped on the side of the road at Fox Hill Lane, Tallaght, in January.
Intelligence received by detectives indicated that Devoy was the bungling hitman who shot Greg Lynch.
Garda detectives on a routine patrol made the discovery of Devoy’s body while two men were in the act of disposing of his body on Foxhill Road in south county Dublin on January 18.
Gardai attempted to pursue the men who fled the scene in a silver hatchback and managed to escape.
Gardai only discovered the body when they returned to the scene at the quiet country lane.
Mr Devoy suffered gun shot wounds to the head and neck and other injuries to his upper body.
He had been wearing a bullet proof vest when the discovery was made and gardai say he had feared for his life.
In 2006 a court heard that Mr Devoy, who had an address at Balbutcher Drive, Poppintree in Ballymun, had more than 60 convictions to his name and it is understood he had just recently been released from prison.
