Five men have appeared in court in connection with a cannabis seizure in Dublin.

Officers from the Garda National Drugs and Organised Crime Bureau searched a house and stopped vans in Palmerstown, Dublin 20, on Wednesday.

Six men were arrested during the operation and five were brought before Dublin District Court today.

Michael Campbell, 31, from New Priory in Donaghmede, was charged with possessing cannabis worth €600,000 for sale or supply on the M50 in Dublin.

Gary Graham, 47, from Patrick Heaney Crescent, his cousin Christopher Graham, 41, of Matt Talbot Court, Barry Keane, 30, of Coolamber Road, Rathcoole, Dublin, and Michael Murphy, 32, of Woodstown Meadow, Knocklyon, were all charged with possessing cannabis for sale or supply at a house on Mill Lane in Palmerstown.

Four of the men were remanded in custody with consent to bail on conditions, including abiding by a curfew and signing on daily at their local garda station.

But industrial cleaner and father of one Gary Graham faced an objection to bail.

Detective Garda Ciaran Cummins alleged he and a co-accused drove to the house in a van. It was alleged a co-defendant left and returned several times in other vehicles.

One was stopped on the M50 and found carrying €600,000 worth of cannabis, it was alleged.

It was alleged another defendant was stopped in Palmerstown and gardai recovered €760,000 worth of cannabis from that van.

Gardai allegedly searched it and found another €670,000 worth of cannabis "stacked against a hedge".

Detective Garda Cummins said the overall value of drugs was in the region of €2m.

In cross-examination with the defence, he agreed that Gary Graham "adamantly denied involvement in the matter".

He also accepted that it was not a case that he attempted to flee or swim in a river.

He agreed Mr Graham did not have the trappings of wealth and that he had the presumption of innocence.

The defence said he had lived at his current address for several years with his family and proposed that he would abide by bail terms and remain in the jurisdiction.

However, the judge remanded him in custody. All the men will appear in court again next week.

A sixth man arrested during the operation remains in garda custody.
