LOOK after yourself and look after your drinks.

That is the message from Bolton police chiefs as they prepare to launch a new scheme to raise awareness of drink spiking in bars, clubs and pubs in the town centre.

Bright yellow labels will be placed on glasses or bottles left unattended, warning: "Your drink could have been spiked. Keep it safe at all times".

The scheme is one of a range of measures being drawn up by the police and Bolton Council to keep the town centre a safe place to party.

Police and landlords will work together to introduce the warning labels in their bars over the next few weeks.

Chief Insp Patrick McKelvey said: "Drink spiking is not a major problem in Bolton and people should not be worried.

"This is just one of a package of measures being launched. People have used drink spiking as an excuse for their own over-exuberance.

"We want to raise awareness of it so that people can have an enjoyable and safe night out."

In another measure, uniformed security men -- likely to be trained door staff -- could soon be patrolling the streets to combat binge-drinking troublemakers.

Government figures also reveal that last year 1,000 people claimed to have been sexually assaulted after "date rape" drugs were put in their drinks.

Chief Insp McKelvey said: "The message is simple. Never leave drinks unattended."

Police are also planning "sting" operations on town centre venues to crack down on under-age drinkers.

Nationally, Home Secretary David Blunkett has warned that town centre violence fuelled by drunken revellers is spiralling out of control.

Look after your drink and look after yourself. "Date-rape" drugs include GHB or liquid ecstasy, valium, tamazepan and rohypnol. Most are clear, odourless and tasteless.
