Firefighters have left the scene of a blaze on Princes Street, but the road remains closed, according to reports from London. The incident is being investigated by the fire service and Police Scotland. The available reports indicate that after the initial response, crews move away from the immediate scene while authorities continue inquiries to determine the cause and circumstances of the fire. While the closure persists, no further details on injuries, damage extent, or suspected cause are provided in the supplied information. Authorities continue to manage the situation through the ongoing investigation, with Police Scotland involved alongside the fire service. The reporting also implies that the emergency phase has ended to the extent that firefighters are no longer at the scene, even though access restrictions are still in place for public safety and investigative purposes. Further updates would be expected once investigators complete their work and any assessments are confirmed.
