A woman has been arrested after an hour-long car chase across Dublin and Wicklow.

Gardaí last night chased a white Mercedes along the M50 from Ballymun to Bray and back again.

The Garda helicopter and up to 20 Garda vehicles tailed the car across the city before it was brought to a halt.

Parts of the chase were streamed on social media.

A woman in her 20s was arrested for dangerous driving.

Gardaí said they were investigating an “incident of dangerous driving” that began when a car failed to stop at Balbutcher Lane in Ballymun at around 5:55pm.

The woman was arrested at Hampton Wood Drive in Ballymun at 6.50pm.
