“We are favoring the theory of an accident,” Remy Heitz told journalists. “No evidence indicates it was an intentional act.”
The French official said 50 people are involved in the investigation into the devastating fire. They are currently questioning workers who were present at the moment the fire broke out.
The devastation of the Notre Dame Cathedral on Monday is the highest-profile loss of France’s historical legacy in decades. The Paris Fire Department deployed 400 people in response to the blaze, which raged for hours before finally being contained.
The fire destroyed two-thirds of the roof and caused the collapse of the spire, which was undergoing reconstruction at the time.
“The fire is completely under control,” Lieutenant-Colonel Gabriel Plus, a spokesman for the Paris Fire Department, told reporters some eight hours after the first responders arrived at the blazing scene shortly before 7 pm on Monday evening. “It is partially extinguished, there are residual fires to put out.”
