Speaking on tonight’s Six One News, junior minister Seán Sherlock described seeing a man running past him “brandishing a sword above his head”.

“It was quite a surreal experience, to be honest, a breach of security but in fairness to the staff here they handled it very well and responded rapidly.

“The sword itself was something you would see in a movie, a typical rapier, if you will. A sidearm of what would be carried by, perhaps a soldier, built into the waist, something that you would take out of a scabbard.

“He wasn’t shouting or screaming or anything like that…He appeared to be quite calm and that’s what made it surreal. I just happened to turn around and see this gentleman bearing towards the doors.

“It was a one in a million incident.”
