Gardai in north Dublin have carried out a series of major raids targeting gangsters who are involved in the supply of heroin and other drugs.
In the latest bust, officers from Swords Garda Station raided three dwellings connected to a feared Traveller gang who are suspected of being involved in the manufacture of pipe bombs.
Around €2,500 worth of cannabis was seized on Wednesday and a man in his 20s was arrested.
The halting site search operation was in the Northern Cross area of Coolock and happened after gardai carried out a number of separate searches in the Edenmore area of Raheny on Tuesday afternoon.
Over €6,000 worth of heroin and cocaine was seized during the Edenmore operation and gardai arrested a 28-year-old man.
He was brought to Store Street Garda Station and questioned by detectives as part of an undercover drugs investigation which has been codenamed Operation Crossover.
Sources have revealed the main targets of the Raheny raids are a crime-based family in the Edenmore area who are suspects in a catalogue of crimes in the locality, including armed robbery.
It can be revealed that many of the suspects are aged in their 40s and 50s and have been terrorising the area for years.
Some of their associates are linked to Gerard 'Bra' Brady, the father of Christy Kinahan cartel mobster Greg Lynch.
Gardai say that both search investigations happened as part of Operation Thor and more operations into both gangs are planned in the future.
"There is no major link between these criminal organisations who are based in the same general locality," a source said.
"Gardai will keep up their investigations into their criminal activities."
Operation Thor has seen gardai adopt a multi-strand approach, emphasising increased visibility, extra manpower including mobile armed garda units, intelligence gathering, tougher bail conditions, awareness campaigns and interaction with community organisations.
The operation costs €5m and has led to the arrests of hundreds of people since it was introduced last November.
