A wheelchair-bound man was robbed by two men who threatened him with a knife.

Police said the 28-year-old was stopped and threatened by the robbers in the early hours this morning.

The man, who has not been named, was outside the Amsterdam pub in Marine Parade, Brighton, when he was approached by the men at about 1.45am.

They threatened him with a knife, which the victim did not see, and demanded cash. The robbers took money and ran off along Marine Parade.
