A 19-year-old man who was being questioned in connection with the murder of Toddy Dooley has been released without charge this evening.
A file on the matter is to be sent to the Director of Public Prosecutions.
Two other men remain in custody in connection with the investigation. They must be released or charged before 11pm.
Toddy (64) was found dead on his living room couch at his house at Sister Senan Court in Edenderry earlier this month, on February 16.
Gardai discovered his body when they were called to the house by his next door neighbour Margaret Farrell.
He had been badly beaten, with injuries to his upper body, and was pronounced dead at the scene.
