A reported bomb threat inside Langevin Block, home of the Prime Minister's Office, led to the evacuation of the building just hours before the throne speech on Wednesday morning.
RCMP Cpl. Lucy Shorey has confirmed police have a person in custody and that Prime Minister Stephen Harper was not in the building, which sits immediately across the street from Parliament Hill, at the time.
UPDATE: Langevin Block has reopened after authorities addressed a security concern involving a suspicious package in the building on Wednesday, according to CTV News.
In a news release, Ottawa police announced the CBRNE (Chemical, Biological, Radiological, Nuclear and Explosives) team βrendered the package safeβ using a robot.
The building was evacuated as a precaution and a joint RCMP-Ottawa police team that deals with potentially hazardous materials was called to the scene.
Shorey declined to provide details about the person of interest or the package.
Global News reports a man entered the building and left a suitcase-sized package.
The incident occurred around 11:20 a.m.
Many reporters in Ottawa took to Twitter to provide real-time updates.
