A number of scramblers were seized in the Ballymun area earlier today as part of a Garda operation.
The seizure comes as Gardaí continue to warn people that they must have a driving license and insurance to use the bikes in public areas.
It follows a recent incident at Darndale Park over the weekend which left a man in critical condition in hospital.
The 39 year-old was hit on the head by one of the vehicles on Saturday afternoon.
Last night, the City Council passed a motion for an emergency meeting to tackle the issue.
