Three men were arrested following the seizures but one has since been released without charge.

Gardaí from the Community Policing Unit at Store St Garda Station were supported by members from the local Detective Units and Crime Prevention Units for the operation which took place yesterday afternoon.

70 smartphones, worth an estimated €15,000, were also recovered.

Three men - aged 33, 30 and 24 - were arrested at the scenes.

One of them has since been released without charge while the other two are being held at Store St Garda Station where they can be kept for up to seven days.
