West Yorkshire Police is joining forces with groups of volunteers in an initiative to reduce sexual offences during the festive season.
Operation Northdale, held annually, sees officers working alongside police volunteers, special constables, ‘street angels’ and night marshals in towns and cities across the county.
The scheme – aimed at raising awareness of the potential dangers of excessive drinking – launches in Leeds city centre this weekend.
Chief Inspector Jaene Booth is briefing those carrying out street patrols.
Free anti-drink spiking devices, crime prevention advice and flyers containing safety messages are being distributed to people on nights out.
She said: “It is important that people know the risks that come with alcohol and the impact it can have on their safety.
“Our teams of officers and volunteers will be out providing reassurance to people, in particular women, and I hope people continue to sit up and take note of these important messages and keep themselves safe and out of trouble.”
