Cause of Notre Dame fire revealed by French police
Investigators think an electrical short-circuit was the most likely cause of the Notre Dame Cathedral fire, according to a French judicial police official.
Investigators made an initial assessment of the cathedral on April 17 but don't have a green light to search Notre Dame's charred interior because of ongoing safety hazards.
The cathedral's fragile walls were being shored up with wooden planks, said the official, who spoke on condition of anonymity because he wasn't authorized to speak by name about an ongoing investigation, Associated Press reported.
Investigators so far believe the fire was accidental, and are questioning both cathedral staff and workers who were carrying out renovations.
A fire broke out at the Notre Dame cathedral in Paris on April 15. The cathedral's lead roof and its soaring spire were destroyed, but Notre Dame's iconic bell towers, rose windows, organ and precious artworks were saved.
