A Dublin TD is demanding that Kinahan and Hutch crime bosses have their assets seized.
It follows the gangland murder of Dubliner Trevor O'Neill, in a case of mistaken identity on the Spanish holiday island of Majorca.
His death comes almost a year after the killing of Gary Hutch in Spain - sparking a deadly feud between the Kinahan and Hutch families in Dublin.
Mr O'Neill, shot dead this week, was a Dublin City Council employee - and has been described as a hard-working, dedicated family man.
Sinn Féin's Aengus O'Snodaigh (pictured) said the Criminal Assets Bureau could have prevented his death: "These gangs and some of their associates in my community are flaunting their wares, the best cars, houses and quite a number of foreign holidays.
"It is only when their assets are targeted that the community rejects them, that gang activity will be at an end."
