I suppose it could depend on what could be called evidence.
A person could complain to the police that their neighbour had stolen their lawnmower and he saw them do it but if there were no other witnesses and no lawnmower was found in the neighbour's possession, there would be no prosecution.
Is that no evidence or insufficient evidence, is an unsubstantiated statement actually evidence?
