Usain Bolt turned up for his first day at work in dapper black suit after his Olympic glory

The 30-year-old fastest man on earth has taken up a role as 'chief speed officer' with a company after completing his historic 'triple triple' at the Rio Games.

He posted a picture in his suit next to his Nissan GTR as he prepared to make the morning commute, before sharing images of himself seemingly sending a tweet on his computer.
