The 'Vitaspirit' which had crashed into a waterside mansion on the Bosphorus on April 7 has been moored in the Marmara Sea for investigations, with the owners of the mansion demanding proper prosecution against those in charge of maritime traffic. It was routed to the Ahırkapı anchor point near Istanbul. There were no casualties or marine pollution caused by the incident. The allision was caused by an abrupt halt of the main engine while en route from the Kerch region to Saudi Arabia, being guided by a harbour pilot. The building’s roof and upper floors collapsed and the basement slumped into the water. A cloud of dust and rubble was sent into the air as the building collapsed. The family that owns the 200-year-old mansion claimed to have lost many valuable properties they had been trying to protect inside and will file a complaint those responsible for maritime security. The wooden Hekimbaşı Salih Efendi mansion was built by Ottoman nobles in the 19th century.
