Cdr Nick John, leading the New Year’s Eve policing operation, said London was expected to be exceptionally busy – particularly the West End – and people should plan how to get home after the celebrations.
He said it was “regrettable” that in recent years there has been an increase in incidents “where a minority have tried to illegally force entry into ticketed events, putting everyone’s safety at risk”.
Anyone trying to gain entry in this way on New Year’s Eve could be arrested and face prosecution, he added.
