Gardaí investigating a murder in west Dublin last month have arrested a man in his 40s.
Ian Tobin, of Fortlawn Park in Blanchardstown, was shot when he answered the door at a neighbour's house and died later in hospital.
The 25-year-old father of two children is thought to have been a victim of mistaken identity.
The arrested man is from the Finglas area and was picked up in Blanchardstown yesterday.
