Investigators have pinpointed the start of the fire that ripped through Notre Dame Cathedral on Monday.
Police sources said after police reviewed a cache of amateur video and photos from local residences, investigators believe the fire started at the center of the cathedral’s roof towards the base of the iconic spiral.
The police source also told CNN that investigators are focusing on two potential problems relating to the outbreak of the fire. One issue under investigation is a possible problem with the fire alarm system sensors.
Investigators’ second line of inquiry relates to the elevators that were built for the construction workers.
Two security guards at the cathedral told police they noticed the flames for the first time only when the flames were already almost 3 meters high.
