A drunk driver in Offaly has been arrested by Gardaí.
They were stopped by officers assisting at the Banagher Horse Fair after they struggled to drive in a straight line.
A roadside test found the driver was five times over the legal limit for alcohol consumption.
The motorist has since been arrested and charged to appear before a sitting of Tullamore District Court at a later date.
