Three men who appeared before special courts held throughout the weekend to deal with dangerous driving activity surrounding the annual Rally of the Lakes have been warned at Killarney District Court they could face jail.

A 25-year-old man could have been driving at a speed of 120km/h through the busy streets of Killarney, Co Kerry, early on Saturday, a court has been told.

Bridges and tunnels on an abandoned railway line, earmarked for a walking and cycling route on the Ring of Kerry, are to be examined to determine their structural condition.
