Reports that the helicopter which has crashed took off from Teesside have been dismissed.
There were reports that the aircraft had flown from Durham Tees Valley Airport (DTVA).
But according to Western Aviation, this is not the case.
A spokesman has said that the helicopter had not set off from the airport.
Original reports stated that Durham Tees Valley Airport was involved and Paul Litten, commercial director for the Humberside Airport, was reported as saying: “This was a private flight from Durham Tees Valley and was due to arrive with our air traffic controllers later this afternoon."
The direct flight path of the helicopter remains unknown.
More details to follow.
