An estimated €500,000 in damage was caused to the aircraft in yesterday morning's attack.

Killaloe District Court heard that peace campaigner Mary Kelly (50) was arrested with a hatchet in her hand.

Ms Kelly, one of the founders of the Peace Camp at Shannon, was charged with causing criminal damage without lawful excuse.

Inspector Tom Kennedy told the court the damage to the plane was put at a minimum of €500,000 and it would be grounded for a number of days.

Seeking that Ms Kelly be remanded in custody, Insp Kennedy said he believed Ms Kelly would carry out further acts of damage and could abscond as she had no permanent address. In order to meet bail, Ms Kelly was ordered to provide €5,000 of her own surety, surrender her passport and leave Co Clare by 6pm last night. She failed to meet the conditions and was remanded in custody to reappear in court on Wednesday.
