A joint campaign between Dutch and Irish police has resulted in the arrest of 13 people suspected of being part of a drugs gang which may have links to Ireland’s notorious Kinahan clan.

In total, eight people were arrested in the Netherlands – three with Dutch nationality, three Irish men and one Belgian, according to Irish media reports. They are suspected of trafficking drugs and money laundering.

Police in Amsterdam also seized 175kg of cocaine, cannabis, vacuum-packed cash, computers, encrypted phones and bitcoin in the raids in the Netherlands, Irish media said.

Dutch police have refused to comment on the arrests because the suspects are being held in solitary confinement and only allowed contact with their lawyers.

In Ireland, where five arrests were made, police found drugs, worth an estimated €7 million at two industrial units in Ashbourne, Co Meath.

Senior Irish police officer assistant commissioner John O’Driscoll  was in the Netherlands on Thursday where he met Dutch law enforcement personnel and law enforcement personnel from other jurisdictions, according to the force’s Facebook page.
