Gardaí in north Dublin are continuing to question a 29-year-old man in connection with the murder of 28-year-old Kevin Ledwidge.
The man handed himself into gardaí in Finglas yesterday afternoon.
Mr Ledwidge was shot dead on the doorstep of his home on Ratoath Drive in Finglas on Sunday.
The two gunmen escaped in a silver coloured Opel Vectra, which was found crashed near the scene.
