Officers from the Criminal Assets Bureau have raided a number of properties in Rathkeale in the past week as part of an ongoing operation.
Several houses in the town are understood to have been targeted in the swoop which took place last Thursday.
A garda spokesman this week confirmed that the raids had taken place but did not reveal the reasons.
“The Criminal Assets Bureau conducted a number of searches in County Limerick on Thursday 11th June 2015,” he said.
“The planned searches were one element of an investigation which is being conducted by the Bureau. For operational reasons no further information is available.”
CAB has previously targeted homes and businesses in the town as part of its investigation into a notorious Traveller gang often referred to as the Rathkeale Rovers.
This gang, based around a small number of close-knit families, is thought to be responsible for much of the illegal rhino horn trade in Europe. However, it is believed to be involved in a wide range of criminal activities throughout Europe as well as North and South America, Asia and Australia.
In September 2013, five home and an office in Rathkeale, Limerick city and Newmarket, Co Cork were raided by officers from the bureau who removed documents and a various items from the properties.
It is not known if last week’s raids were related to this ongoing operation.
