The man will appear at Kilmainham District Court this morning at 10.30am.
A second man arrested in connection with the incident remained in custody last night.
Detectives picked up a 20-year-old man yesterday morning and followed with the arrest of a youth in his late teens early in the evening.
The death of Thomas Farrell, a father of two girls and three boys aged between seven and their early teens, has stunned the west Dublin community of Ballyfermot. The 43-year-old removal van driver was stabbed once in the back in the hallway of his Cherry Orchard Avenue home after he confronted two young men attempting to steal his car. As he turned and walked back into the house, one of the men produced a knife and stabbed him in the back. It is thought the knife pierced Mr Farrell’s lung.
All five children were in the house and two of them are believed to have been present when Mr Farrell was stabbed. The screams of their mother Gráinne alerted neighbours who called emergency services. Mr Farrell died four hours after the attack in St James’s Hospital.
He underwent emergency surgery but lost his battle for life shortly before 2am yesterday, despite earlier showing signs of recovery. Detective Superintendent Hubert Collins, who is leading the murder investigation, appealed for information from anyone who may have noticed persons acting suspiciously in the area between 8pm and 8.30pm on Wednesday. The scene was sealed off yesterday for forensic examinations.
Mary Upton, Labour TD for Dublin South Central, condemned the killing and offered her sympathies to the family. “I am calling on the whole community in Cherry Orchard to stand up against this wicked anti-social behaviour and to help the gardaí with their inquiries.”
