Drinkers are being urged to use anti-spiking devices like these
Revellers in Bradford are being urged to make sure they don't fall prey to having their drinks drugged - or 'spiked' - during an evening out.
West Yorkshire Police and Bradford Street Angels will be handing out anti-spiking devices this weekend.
It's part of what's called Operation Northdale, four weeks of action designed to reduce sexual offences.
Imran Hussain, deputy leader of Bradford Council, warns: "Prevention is far better than cure."
Councillor Hussain will be joining West Yorkshire Police and volunteers from Bradford Street Angels to offer the small anti-spiking devices - known as Spikeys - to drinkers free of charge.
When pushed into the top of a bottle, they lock onto a straw making it more difficult to slip drugs into drinks.
Councillor Hussain, who is also executive member for community safety, says: "We want to ensure people are aware of drink spiking and the potential pitfalls of having too much to drink.
Bradford's revellers are to be warned of the dangers of 'spiked' drinks
"By working together we can continue to drive down crime."
Operation Northdale is described as a preventative operation and it is being emphasised that there is no evidence to suggest drink spiking or sexual assaults are worse in Bradford than in any other major UK city.
John Dinsdale, chair of Bradford Street Angels - a church-based organisation whose volunteers patrol Bradford city centre on Friday and Saturday nights making sure revellers are safe - says their message is simple.
He explains: "We are urging people to keep an eye on their drinks and not overdo it.
"To help stay safe, people can add the contact telephone number of a reputable taxi firm to their phones and agree to watch out for each other before leaving for a night out."
Chief Superintendent Alison Rose, chair of Bradford District Safer Communities Partnership, says she has nothing but praise for everyone who is trying to make Bradford a safer place in which to have a good time at the weekend.
She says: "The partnership working in Bradford is first class.
"I have seen evidence of the effective way in which the voluntary sector has helped to reduce the terrible harm that rape can inflict on vulnerable victims.
"These are extremely seriously crimes and West Yorkshire Police will do everything in our powers to ensure offenders are brought to justice."
