POLICE have issued an update after concerns of drink and drug spiking in Herefordshire.

West Mercia Police are encouraging anyone who thinks they have been injected, or had their drink spiked, to report it as soon as they can.

Although the opportunity to inject a significant amount of drug is limited, it is possible, West Mercia Police said.

The force said it will investigate every report of spiking.

If the crime is reported within five days will take a urine sample, however, the sooner the crime is reported the more effective the sample, the force said.

Assistant chief constable of West Mercia Police Damian Barratt said it was a serious crime.

“We know that in the run up to Christmas more and more people will be visiting pubs and clubs across Herefordshire and will be increasing the number of officers on patrol," he said.

"Our plans for the Christmas period will complement our existing plans to help keep people safe by targeting predatory behaviour and those looking to exploit people enjoying a night out.”

West Mercia Police shared information gathered by West Midlands Police from scientists.

"Because of the body’s natural response to the pain that comes from a needle being pressed into the skin, most people react very quickly to being injected and move away from the pain," West Midlands Police said.

"This reflex response combined with the time needed to press the syringe plunger, means the opportunity to inject the significant amount of drug needed to have an effect is limited, but not impossible."

Constable Barratt said although he hoped people would find this information reassuring, it would not make police complacent in their response to drink or drug spiking.
