Heathrow Airport fire not criminal, police confirm

British police have concluded that the fire at an electricity substation, which caused Heathrow Airport to shut down for 18 hours, is no longer being treated as a potentially criminal matter. The Metropolitan Police's Counter Terrorism Command found no evidence suggesting suspicious circumstances surrounding the incident. This fire, which occurred on March 21, stranded over 200,000 passengers and resulted in significant travel disruptions. Investigations into the fire's cause are ongoing, with collaboration from the National Grid and local fire services. Both the government and Heathrow Airport are conducting reviews to assess the situation and improve infrastructure resilience. The police will continue to monitor for any new information that may arise.
