Earlier on Tuesday, Paris public prosecutor Remy Heitz said that there is no sign the 15 April Notre Dame Cathedral fire was started on purpose, adding that an accident remains the most likely cause of the blaze.
Alice Weidel, a parliamentary group leader of the right-wing Alternative for Germany (AfD) Party, has suggested a connection between the Monday blaze which seriously damaged the Notre Dame Cathedral in Paris and previous anti-Christian attacks in France.
Heitz assured that all means would be used to define the cause of the fire and confirmed that witness hearings are still in progress.
