Gardaí have revealed three drivers were driving more than 40 kms over the 100kms per hour limit in Donegal and Westmeath, as part of a 24-hour crackdown on speeding.

More than 66,000 motorists had their speed checked by gardaí in under 10 hours as Operation Slowdown delivered on its promise of an intensive nationwide scrutiny of driving habits.

A man knocked down and killed in an accident involving a Garda patrol car was a Gaelic footballer.
