World rally star Colin McRae and his young son were feared dead after his helicopter crashed and exploded near his Scottish home.
The 39-year-old driver was thought to be at the controls of the French-built Squirrel helicopter with his son Johnny, five, as a passenger when it crashed a mile from the family farm in Lanarkshire just after 4pm.
Police confirmed that at least one person had died but said the helicopter was so badly damaged by fire that they were not immediately able to confirm how many people were on board.
The ambulance service said they had not been asked to attend to any casualties and had been asked to stand down soon after the crash.
Sources close to the family said they believed Colin and his son had both died.
McRae, the 1995 world rally champion who became known to millions after lending his name to a top-selling series of computer games, is a qualified pilot and regularly flew the helicopter from his home, Jerviswood Farm, just outside the town of Lanark.
It is believed he was on his way to Glasgow when the helicopter came down.
