Nine treated in Liverpool after mephedrone use
Nine people have been treated at a Merseyside hospital after they were suspected of taking mephedrone.
The seven men and two women were taken ill after socialising in Wood Street, Liverpool on Saturday evening, police said.
The group, aged in their late teens to 20s, are believed by officers to have taken the mephedrone.
Samples of the substance are undergoing forensic analysis. All nine were treated and released from hospital.
Merseyside Police said inquiries were being made to establish where the mephedrone was bought.
Det Ch Insp Tracey Hayes said: "We are keen to trace anyone with any information about this incident, or have any information about people or premises supplying mephedrone in Liverpool which could have had potentially tragic consequences.
"We urge people to be on their guard and not to eat or drink substances that are not for human consumption as it could prove extremely harmful or even fatal."
Mephedrone, which first appeared in the UK in 2009, was sold legally until it was classified as a Class B drug by the government in 2010.
