London commuters are being encouraged to take a walk on the wild side by capturing a lion on the loose.

LeoVegas.com, the UK’s leading mobile casino, has unleashed a number of lions onto the pavements at the entrance of 15 tube stations around central London.

Leo the Lion has been sprayed as street art onto a number of dirty streets, using ‘clean advertising’ which helps remove dirt from London’s busy streets. Passers-by lucky enough to spot Leo are being asked to tweet pictures to @LeoVegas using #LuckyLion. Five lucky winners will receive an iPad mini.
