National Police Chiefs' Council Lead for Violence Against Women and Girls, Deputy Chief Constable Maggie Blyth, said:
"Women and girls on nights out across the country, will be concerned by what they have seen on Channel 4's Undercover: Sexual Harassment — The Truth. We want you to know that the police are there to help you if you need us and you will be listened to.
"Policing takes any form of abuse or behaviour driven by sexism or misogyny seriously. Both Merseyside and the Metropolitan Police have contacted the programme makers to obtain further information in order that offences of stalking and harassment can be proactively and professionally investigated.
"Policing is committed to tackling violence against women and girls.
"We will relentlessly pursue violent and abusive men and root out toxic misogyny and abuse in our own ranks and in society to ensure that women and girls, wherever they are, feel safer."
