Deadly blue and green pills which have killed two people in London have finally been identified.
The pills, which are marked with the number ’80’ on one side and possibly ‘OP’ on the other, contained nitazenes which can be up to 500 times stronger than heroin.
A 28-year-old man and a 20-year-old woman died in Southhall, west London, on May 26 after taking an ‘illicit substance in the form of a green pill’, Met Police said.
The pair are believed to have visited a nightclub in south London, and their bodies were discovered the next day at a home in Ealing.
One more person is said to have been hospitalised after taking the pill, and London nightclubs have urged people to stay away from the drug.
The Cause, in east London, said: ‘We have been made aware of dangerous Blue/Green Pills marked with an “80”.
