Liberal Leader Justin Trudeau's home in Ottawa was broken into overnight, his office confirmed Saturday.

"Early [Saturday] morning, the Trudeau family discovered that their family home had been broken into. Ms. Grégoire-Trudeau and the children were asleep at the time of the incident, and Mr. Trudeau was working in Winnipeg," a statement from spokeswoman Kate Purchase said.

Everyone in the family is safe, and nobody was harmed, she added. Both the Ottawa police and the RCMP are investigating the incident.

Although The Ottawa Citizen cited an Ottawa police source saying that a note on the back patio had been left advising the owners to keep their doors locked in case of theft, The Huffington Post Canada was told the note was "threatening." A source with close knowledge of the incident described it as "very serious." Nothing, however, was stolen.

Trudeau told CBC Saturday his family was shaken by the incident.

"Obviously we are extremely troubled with this," he said. "My family has decided they're actually going to join me in Montreal today because they don't want to stay in the house tonight."

Trudeau, as the leader of the third party, has no RCMP detail.

The Liberals have asked the Mounties to assess the situation. A government source said police would only provide security if they "believe" there is a threat.

The Ottawa Police Service told HuffPost Canada they could not comment on the investigation because it was "ongoing." Calls to the RCMP were not returned.

This isn't the first time the Trudeau has been the target of unwelcome attention. Last year, a 41-year-old Montreal man was arrested for allegedly harassing Trudeau and his campaign team.

Purchase said the Liberal leader wanted to "thank people for their concern at this time."
