Gardai from the Cork Divisional Drug Unit searched a house in the Dillons Cross area of Cork city on the evening of 22 December 2011 and seized herbal cannabis, initially valued at about 250,000 euro, arresting two men aged in their thirties and forties.[1] The men were detained under drug trafficking legislation at Gurranabraher and Mayfield Garda stations.[1]

One of the men, Denis Flynn, 44, of Upper John Street in Cork, denied having 20 kg of cannabis for sale or supply at Harringtons Square, Dillons Cross on that date, but a jury convicted him after a trial at Cork Circuit Criminal Court in February 2013 and he was held in custody from 26 February.[2] The court heard the drugs were worth 240,000 euro.[2]

Detective Garda Tony Holmes told the trial he had watched Flynn drive a Toyota Corolla into Harrington Square, meet another man and hand over a black refuse sack and a grey holdall that were later found to hold the 20 kg of cannabis, with traces of cannabis later found in the boot of Flynn’s car.[2] On 29 April 2013 Judge Sean O Donnabhain imposed 10 years, backdated to 26 February, saying it was the minimum available because Flynn had a previous conviction for possessing 3,000 euro of cannabis for sale or supply in 2010, for which he had served nine months.[2]
