Train passengers were left shell-shocked after discovering a live crab - sitting in its own seat.

The crabby commuter - who has been named Craig - was found on Wednesday evening on a South Western Railway service from London to Portsmouth.

Train driver Mark Walsh was approached by a passenger about the crustacean and at first thought it was a joke - until he saw the seat pincher.

Mark says that Craig was quite poorly from the journey, but they dropped him off at a park with a pond in Southsea.

The driver speculated that the crab might have escaped from a fisherman's box or have been placed as a prank by schoolchildren.
