A woman was arrested in Dublin this evening on suspicion on drink-driving after the Garda Commissioner intervened in a road traffic incident.
Drew Harris was being driven back to Garda Headquarters at around 5.30pm when he saw a car being driven in an erratic manner in Blanchardstown.
The Commissioner contacted the Roads Policing Unit and the woman was stopped.
She was subsequently arrested and tested for alcohol and is expected to be prosecuted.
Garda Headquarters confirmed that the Garda Commissioner was present at a road traffic incident during which a driver was arrested for a road traffic offence.
In a statement, it said An Garda Síochána will not be making any further comment.
