A file has been sent to the Director of Public Prosecutions following the release of two men arrested yesterday by gardaí investigating the murder of Darren Guerrine in Dublin more than four years ago.
The 21-year-old was shot in the back of the head with a shotgun at point blank range on the banks of the Grand Canal at the back of the Jamestown industrial estate in February, 2008.
Guerrine, of La Touche Road, Bluebell, Dublin 12, had a number of convictions for road traffic offences and public order incidents but the motive for his murder was unclear. He was not known for involvement in serious or organised crime
He was facing charges relating to an incident in the midlands when he was caught driving a stolen car and was facing charges of careless driving and drink-driving in relation to the same incident.
The two men arrested yesterday were held at Kilmainham Garda station under Section 30 of the Offences Against the State Act 1939.
One of the men is in his late 20s and the other is in his mid 30s, a Garda spokesman said. Both men were released without charge.
Four people were arrested and later released in connection with the killing in March, 2008.
