A delivery man was so desperate not to let thieves get away with his van that he clung onto the roof of his motor for a mile - in his underpants.
The Polish driver may have been taking tips from Tom Cruise - but got confused between Risky Business with Mission Impossible and so chased after the stolen van in his briefs.
He spotted the two thieves breaking into his van from his hotel room window in the suburb of Villemomble, Paris.
Wearing only grey pants, socks and a jumper he raced through the building and managed to clamber onto the roof of his van as the thieves drove off.
The half dressed crime-fighter clung on for a mile as the thieves sped through traffic.
