Local police are still concluding their investigation into the fire but have announced the fire was caused by a short circuit which ignited a high-density battery that is part of the high-performance charger used in MotoE. The source of the short circuit is yet to be confirmed.
Never in a million years would a Police force be qualified or experienced enough to conduct a/any fire investigation.
