Eleven properties in Limerick were raided by gardai last night as part of a national operation targeting prostitution, brothel keeping and associated offences including money laundering.
The properties, which are all located in the city centre, were searched as part of Operation Quest, which began at midday yesterday.
More than 200 gardai across the country were involved in the operation, which also extended into Northern Ireland and involved members of the PSNI.
Sean Mac Seoin of the Garda Press office said a large amount of documentation, cash, mobile phones and computers were seized during the operation.
It is understood that up to 20 prostitutes and a number of male clients were encountered by gardai during the searches of brothels in Limerick. However, no arrests were made.
Chief Supt David Sheahan said he was "very satisfied" with the results of the search operation in Limerick.
