Lewis Hamilton led tributes from the Formula 1 world after the death of motorsport legend Ken Block.
The 55-year-old died on Monday as a result of a snowmobile accident in Wasatach County, Utah. Police said Block was riding a snowmobile on a steep slope which then upended and landed on top of him. He was pronounced dead at the scene of the crash.
Block made his name rallying in American and around the world, before moving on to rallycross later in his racing career. He also became a star on YouTube promoting gymkhana, co-owned the Hoonigan Racing Division and appeared on BBC TV series Top Gear.
