OTTAWA — A man carrying a concealed knife on Parliament Hill has been arrested by the RCMP.

Cpl. Valerie Thibodeau, a media relations officer for the Mounties’ national division, says Parliamentary Protective Services apprehended the man outside Centre Block, the main building on Parliament Hill that houses the Senate and the House of Commons.

She says the man is in custody as the RCMP continues to investigate and there is no further information to disclose at this time.

Security on the Hill has been tightened since Oct. 22, 2014, when a gun-toting murderer, Michael Zehaf Bibeau, managed to sprint across the lawn and through the main doors into Centre Block.

Zehaf Bibeau had just gunned down a soldier standing guard at the nearby National War Memorial.

Zehaf Bibeau died in a hail of bullets just outside the door to the Library of Parliament.
