Peter Hore invades ICAC hearing
A security guard is injured when "serial pest" Peter Hore invades the Independent Commission Against Corruption's hearing room in Sydney. Kate McClymont reports.
As two special constables rushed to restrain him, he yelled "don't assault me" repeatedly before other officers ran into the room.
He was pinned to the floor and dragged away with his hands behind his back. One constable sustained a head injury and was bleeding. He was assisted by a journalist and ICAC staff.
Commissioner Megan Latham said some ICAC staff were "traumatised" after the incident and the inquiry would take an adjournment of half an hour.
"I'm going to take an adjournment," the commissioner said.
"There are a number of staff who are quite traumatised by what happened. There is an ambulance on the way. I think it would be wise if we took half an hour out to settle down."
Just before 11am the man burst into the hearing room, shouting about his "brother" being killed in Newcastle last week. He also shouted out about being "president" as he tried to rush towards the bench where the commissioner was presiding.
Security scare at Sydney ICAC hearing
Serial activist Peter Hore causes a disturbance during the Independent Commission Against Corruption in Sydney on Friday morning. Nine News.
Last month, a man with whom Hore shared a house in Newcastle was found dead, presumed murdered, in a local park. His arms and legs had been trussed up and the lower half of his body was naked.
Two armed special constables, a male and a female, tried to restrain Hore. As the male constable grabbed his arm from behind, Hore lunged backwards and the male constable hit his head on the corner of a table as horrified barristers moved away.
It took several ICAC officers to restrain the man, who was finally handcuffed out in the corridor. He was ushered into a lift by staff.
Hore was driven away in a paddy wagon shortly before midday, banging loudly on the walls in the back.
The commissioner urged anyone who captured footage of the incident to come forward because it may be required by police.
The inquiry resumed at midday.
Hore has been labelled a "serial pest" after a string of similar public stunts, include gatecrashing the funerals of former INXS frontman Michael Hutchence and racehorse trainer T.J. Smith.
He has also invaded the NSW and South Australian parliaments, Flemington racetrack during the Melbourne Cup and the pitch of a Socceroos World Cup qualifier against Iran.
He also once charged Sarah Murdoch on stage during a lingerie launch at Brisbane.
