Police have arrested a man who was asleep at the wheel of his car with a bag of marijuana on his lap. Officers in Cleveland in the US went to investigate the truck parked outside a bar with its lights on. They say the driver believes he fell asleep while rolling himself a joint. Before waking him police sergeant Mark Clark took pictures for evidence according to the Plain Dealer newspaper. Middlefield police Chief Dave Easthon says the man admitted the offence and was due to appear in court next week.
