Canadian police have arrested an armed man who had gained access to the Ottowa estate which includes the official residences of the prime minister, Justin Trudeau, and the country’s governor general.
Neither Trudeau nor the governor general, Julie Payette, were present at the time of the incident early on Thursday, police said.
Trudeau and his family are based in a large house on the 88-acre (0.35 sq km) grounds of Rideau Hall, the residence of Payette, the official representative of Queen Elizabeth.
“At approximately 6:40 this morning (10:40 GMT), an armed man was able to access the grounds … the prime minister and the governor general were not present at the moment of the incident,” the Royal Canadian Mounted Police said on Twitter.
“The man was arrested shortly after without any incident. He is currently in custody and is being interviewed,” it added, saying criminal charges were pending.
A spokesman for Trudeau confirmed that the 48-year-old prime minister was not at home at the time. Trudeau, who is married with three children, also has access to a summer house about 22 miles (35km) northwest of Ottawa.
Unlike the United States, where four presidents have been assassinated since 1865, there is almost no history of serious political violence in Canada.
The one exception was in 1970, when a radical group seeking independence for Quebec kidnapped the Canadian province’s deputy premier and later killed him.
Trudeau donned a bulletproof vest for an election campaign rally in October last year after officials detected a security threat.
