Vandals have defaced the tomb of one of Canada's most charismatic former prime ministers.
Quebec provincial police discovered the words "FLQ" (Front de liberation du Quebec) and "traitor" painted in black on the family crypt of Pierre Elliott Trudeau on Saturday in Saint-Remi, south of Montreal.
"We don't know exactly what happened, we suppose it happened during the night," said police spokesman Sgt. Gregory Gomez del Prado.
He would not say how police were notified.
There have been no arrests and police have launched an investigation, he added.
The Front de liberation du Quebec was a terrorist group in Canada that supported the Quebec sovereignty movement. Members were responsible for more than 200 bombings and the deaths of at least five people, which culminated in 1970 with the October Crisis, when a British diplomat and a Quebec provincial cabinet minister were kidnapped. The minister, Pierre Laporte, was killed.
Trudeau made enemies during this crisis by invoking the War Measures Act, which gave the government sweeping powers of arrest and detention without trial.
The former leader was known for establishing the constitutional Charter of Rights and Freedoms, which guarantees certain political and civil rights for all Canadians.
Trudeau served as Canada's prime minister 1968-79 and 1980-84. He died in September 2000 at age 80.
