This from the BBC News website: Fresh warning over 'bad heroin' Officers say the deaths of four drug users may be related Police have cautioned drug-users about a suspected batch of bad heroin after two men were found dead in east London. One victim, 30, was found at a house in Ilford Lane, in Ilford, while another man, 50, was discovered in Valentines Park, in Ilford, clutching a syringe. The latest warning comes just days after two other drug-users were found dead in south London. Officers say both incidents may be related. Officers in Redbridge said the batch of narcotics was "particularly lethal". Local circulation Both victims, who were discovered on 5 November, are yet to be identified but police believe that both men may have purchased the drugs locally. Det Insp Ronan McManus said: "The batch of heroin that seems to be in circulation at the moment appears to be particularly lethal and by putting out this warning we can help people make informed decisions. "We also urge anyone who may get into difficulties and become ill through the use of drugs to seek medical help as soon as possible," he said. On Thursday, police in Lambeth in south London warned drug-users about a batch of 'lethal' drugs in circulation locally.
