The healthcare worker, understood to be called William, landed at RAF Northolt near Heathrow just before 9pm on board a specially equipped C17 plane. An ambulance transporting the man to an isolation unit at the Royal Free Hospital in north London travelled there under a police escort to stop other vehicles from interrupting the journey.

Health chiefs insist the risk to the British public from ebola, which kills up to 90% of those who get it, is "very low".
Deputy chief medical officer Professor John Watson said: "We have robust, well-developed and well-tested NHS systems for managing unusual infectious diseases when they arise, supported by a wide range of experts.
"UK hospitals have a proven record of dealing with imported infectious diseases and this patient will be isolated and will receive the best care possible."

Ebola is contracted through contact with an infected person's bodily fluids and there is currently no cure or vaccine.
Strict quarantine measures are used to stop the spread of the virus, as well as high standards of hygiene for anyone who might come into contact with sufferers.
Symptoms of the virus appear as a sudden onset of fever, headache, sore throat, intense weakness and muscle pain.
