Gardaí are clamping down on rogue taxi drivers attempting to rip off tourists on their way into Dublin city centre from the airport.

Checkpoints set-up near the airport have detected a number of drivers failing to take the shortest route into town – while others have been caught overcharging.

On Monday, five drivers were caught taking the long road into town after a checkpoint was set up on the Malahide road.

In the last two weeks, 11 taxis have been detected for failing to use the shortest route and three for overcharging.

Drivers caught taking longer routes can face prosecution and a fine of up to €2500.

Overcharging can result in a fixed charge penalty notice carrying a €60 fine.

Gardaí said they will continue to work with the National Transport Authority (NTA) in setting up further checkpoints throughout the summer months.

A garda spokesperson said that the clampdown is targeting a small number of rogue drivers – with the vast majority fully compliant with current rules.
