Eleven members of a criminal gang have been arrested and charged by detectives who have seized the UK’s largest ever stash of synthetic opioids. Detectives working with the UK Border Agency raided a number of addresses in Waltham Forest and Enfield on 24 October. It was part of a national UK law enforcement effort to investigate the increase in synthetic opioid products being adulterated into the drugs supply network. At an address in Waltham Forest they recovered approximately 150,000 tablets of Nitazene, a synthetic opioid, in a sophisticated factory set up. A substantial amount of other class A and B drugs, a firearm, a pill pressing machine, over £60,000 in cash and £8,000 in cryptocurrency stored in various hard drives were also seized, along with a large quantity of mobile phones and laptops. It is suspected the drugs were sold via the Dark Web, using encrypted chat applications and social media. Eleven people have been arrested between 21 August and 21 November. All have been charged with conspiracy to supply class A and B drugs Detective Superintendent Helen Rance, leading the investigation, said: “Synthetic opioids have been detected in batches of heroin found in London and across the UK; they substantially raise the risk of incredibly serious harm to the user and are believed to be linked to a number of deaths. “We are working closely with partners to monitor and proactively tackle this issue, provide advice and remove the availability of these dangerous drugs from our streets.” Anyone wanting to provide information, seek advice or request help should contact their Local Drug Information System (LDIS) or www.talktofrank.com or from the FRANK helpline on 0800 77 66 00.
