Canadian police said a man was arrested late Saturday after parliament was closed for several hours in Ottawa, the Canadian capital, the Associated Press (AP) reported.
Investigators said a man gained unauthorized access to the East Block of the Canadian Parliament on Saturday afternoon and barricaded himself inside the building.
In a social media post hours later, police said the man was taken into custody without incident.
There was no mention of accusations or motives.
Police initially issued an alert on Saturday afternoon telling anyone in the East Block, which houses parliament offices, to seek shelter in the nearest room, close and lock all doors and hide.
People were evacuated from the building, and police closed a significant portion of Wellington Street in front of Parliament, blocking traffic and pedestrians.
Police Inspector Mark Bouwmeester told reporters that the circumstances of the incident were "suspicious," but gave few details about what happened inside.
