The trial of 'Cranberries' singer Dolores O'Riordan on air rage allegations has been put back for medical reasons.

The 43-year-old was arrested at Shannon Airport last November, after flying in from JFK Airport in New York.

Gardaí were on standby at the airport, after they were notified that a passenger had become disruptive on board the Aer Lingus flight and had to be restrained.

She faces four charges including assault.

O'Riordan has been charged with assaulting two airport police officers and a garda, and is also accused of resisting arrest.

But her legal team has asked for the case to be delayed as she continues what has been described as 'residential treatment'.
