The Criminal Assets Bureau (CAB) is urging people to report any suspicious activity in their community.
In a new initiative among the public, CAB wants to hear about people who have expensive homes and luxury cars but don’t seem to have the income to match it.
Over 300 CAB investigations are currently underway in Dublin.
The crime-fighting agency has seized tens of millions of euro in assets from criminals since it was established in the 1990s after the murder of journalist Veronica Guerin.
A CAB spokesperson said: "We're asking people: do you suspect somebody's lifestyle is funded by crime?
"Has somebody got a Range Rover or some large vehicle?"
"Contact CAB today so we can make them pay and take it away."
