A helicopter has crashed into the sea near the Flamborough lighthouse, just off the East Yorkshire coast.
Following an emergency call from a member of the public at approximately 1.40pm, the coastguard, police and ambulance services attended the scene.
An eyewitness, Ron Marwood, said the helicopter was a “small, white” craft with not more than two or four seats. He said that he heard a change in the pitch of the engine as it flew past and then it “just disappeared down below the cliffs.”
A spokesperson for the Humberside Police said: “An area has been cordoned off while the emergency services and coastguard continue their work. Initial inquiries are being made in order to try and establish the circumstances which led to the helicopter coming down.”
The emergency services have warned members of the public to stay away from the crash site as there is aviation fuel in the water and dangerous cliffs in the vicinity.
It is thought that the helicopter is not a British military aircraft.
