PARIS (AP) — A preliminary investigation found no evidence to suggest that a fire that gutted large parts of Notre Dame Cathedral was criminal, the prosecutor’s office said Wednesday.The prosecutor’s office said in a statement that several hypotheses about the cause of the April 15 blaze include a malfunctioning electrical system or a smoldering cigarette — to be further investigated in a new probe.The prosecutor’s office announced the opening of a judicial investigation led by three judges for “involuntary degradation by fire through manifestly deliberate violation” of security rules or simple imprudence.
