Herts Police will be out in the town centres and outside nightclubs across Dacorum over the festive period, as part of their rape and sexual assault prevention campaign.
The main aim of proactive patrols is to get the message directly across to revellers that sex without consent is rape.
Pre-Christmas activity has already included speaking to taxi companies, licensees and door staff to raise awareness about looking out for, and taking care of, people who may be vulnerable because they have had too much to drink.
Police and Crime Commissioner David Lloyd, said: “This campaign aims to prevent serious sexual assaults during the party season, and beyond.
“Increased understanding and awareness can only reduce the number of incidents happening.”
If you have been the victim of rape or sexual assault, you can report it in confidence to police on 101. Alternatively you can call the SARC (Sexual Assault Referral Centre) on (Freephone) 0808 178 4448.
