An 18-year-girl has died after taking what is believed to have been an Ecstasy-style tablet.
The teenager was rushed to the Royal Liverpool University Hospital on Sunday after
allegedly taking a lime-green 'Rock Star' pill with a five-pointed star motif.
The Liverpool Echo reports that the teenager was with a friend in Walton, Merseyside, when she complained of feeling ill. She was subsequently taken to hospital by ambulance, but died a short time later.
Her name has not yet been released, but her family have been informed and a post mortem examination is due to take place today (Tuesday).
Merseyside police have now issued an urgent warning about the 'Rock Star' drugs. In an official statement, they said:
"Detectives believe that the deceased may have taken a green coloured 'Rock Star' Ecstasy tablet shortly before she died and as a precautionary measure they are warning people not to take this type of tablet. "
They added that 'inquiries are underway to find out where the tablets were bought', and urged members of the public with any information to contact them.
If the teenager's post mortem reveals the drug did cause her death, it will be the second time a teenage girl has passed away after taking Ecstasy-type substances on Merseyside. In June, 2012, 15-year-old Rose Farley fell ill at an 18th birthday party, and an inquest into her death later revealed she had died from the effects of MDMA (Ecstasy). Rose's friends believed her drink had been spiked, and the inquest was adjourned pending criminal proceedings.
