An 82-year-old spent more than 30 hours on a motorway after getting lost driving an hour away to his daughter’s house.
Dennis Leighton sparked a police appeal for help tracing him after leaving his home in Windsor, Berkshire, on Monday evening.
The pensioner had made the 55-mile journey to his daughter’s home in Swanley, Kent, before but got lost on the M25.
The trip should have taken him just over an hour. When he did not arrive his concerned family phoned the police.
He was eventually found in south London by Metropolitan Police yesterday morning after spending two nights in his car.
Officers think he might have spent a large part of the time parked in a layby or services.
A Thames Valley Police spokesman said: “He got a bit lost but was found safe and well in the early hours of yesterday morning.”
