The Criminal Assets Bureau has confiscated two mobile homes and two Audi A6 cars from people linked to the ongoing feud between organised crime groups in Drogheda, Co Louth.
The High Court has deemed them to be the proceeds of crime.
The assets were identified as part of Operation Stratus set up to target the criminal gangs involved in drug dealing, shootings and other feud-related activities.
The mobile homes are valued at €20,000 each, with the cars worth €20,000 and €14,000 respectively.
They were identified for confiscation by a local Garda Divisional Asset Profiler.
Chief Superintendent Christy Mangan described the seizure as a significant outcome and said gardaí will continue to target the gang's money and property.
Four men have been shot dead as part of the feud and there have also been more than 90 attacks including shootings, petrol bombings, arson attacks, assaults and two attempted murders.
