A woman has admitted making bogus bomb threats to Áras an Úachtaráin, Leinster House and the offices of various TDs.

Anne Fennell of Monastery Gate Green, Clondalkin in Dublin said she was really annoyed about water rates and other things in the news at the time.

Just after 9am on the morning of October 18 2014, an usher at Leinster House took a call from a woman who claimed there would be a bomb left outside the main gate at 3pm.

The threat was taken seriously and the building was searched before it was eventually declared a hoax.

That was just one of a series of similar calls made by Anne Fennell between March and November 2014.

During a call to the Áras ahead of the President’s historic visit to the UK in April of that year, she warned the receptionist that both Michael D Higgins and his wife Sabina would be returning to Ireland in plastic bags if they set foot on English soil.

The offices of various TDs were also targeted. The court heard an assistant at the constituency office of Alan Kelly was told both he and the Minister for the Environment would get a bullet in their heads.

Fennell admitted everything following her arrest and said she never intended to carry out any of the threats. A sentence will be handed down in July.
