Detectives investigating two fatal shootings in Dublin have refused to speculate on motives for the gangland-style killings.
Trevor Walsh, 33, was shot dead outside a house in Finglas in the early hours of yesterday morning.
Detectives say a lone gunman wearing a hooded top fled the scene on a bicycle.
Less than 12 hours earlier, Anthony Foster was shot dead as he left his girlfriend's flat in the Coolock area.
No description has been given for a suspect in that murder.
It is not clear if the two are linked, but both men had criminal records and had been involved in drug dealing.
