A man has been arrested as part of searches carried out by officials from the Criminal Assets Bureau investigating the activities of a criminal gang.

Today's raids were part of an investigation by the CAB into the activities of a Cabra-based criminal gang and two brothers in their 30s.

Armed officers from the Emergency Response and Armed Support Unit as well as the drugs and organised crime bureau were involved.

24 homes and businesses were searched in Cabra, Finglas, Monkstown, Leixlip, Courtown and Gorey.

Gardaí seized a large amount of documentation and evidence that they believed relate to the proceeds of crime.

One of the houses in Wexford was built for over 1 million and included a gym and a pool table.

During a search of a house in Finglas around 3,500 worth of cocaine was discovered and a 37-year-old man arrested.

Small quantities of cash and a car were also seized.

It is understood the investigation is focused on the purchasing of properties as part of suspected money laundering.
