Footage has emerged of the moments after Sergeant-at-Arms, Kevin Vickers, shot dead a gunman who had attacked the Canadian parliament in Ottawa.
Mr Vickers can be seen calmly walking down a corridor inside the parliament, minutes after he shot the gunman - who was reportedly a Muslim convert named Michael Zehaf-Bibeau.
Mr Vickers received a standing ovation from politicians when he returned to parliament on Thursday.
