It comes a day after North Yorkshire Police were forced to issue a warning to parents asking them to stop their kids from gathering in large crowds and committing antisocial behaviour offences.The official guidance is that people should not go out in groups and anyone out in public should maintain a social distance of at least two metres.

Everyone is being asked to stay home as much as possible for as long as possible, even those without symptoms.

NHS workers in Armley this morning issued a plea to the public, stating 'We're at work for you. Please stay home for us'.
