A TEENAGER was critically injured in an accident while out sledging.
The 16-year-old suffered "life-threatening" head injuries after falling off a toboggan at speed in Middlesbrough.
He was airlifted to hospital and is said to be fighting for his life.
A Great North Air Ambulance spokesman said crews were called to land near Flatts Lane Country Park at 1.25pm today.
The spokesman described the boy's injuries as life-threatening, adding: "He was given an anaesthetic at scene before being transported to the James Cook University Hospital in Middlesbrough in a critical condition."
A road ambulance also attended the incident.
The air ambulance spokesman said further details may be released later.
