County lines: Girl drug runners in the UK

New figures released in the UK have revealed at least 4,000 young people are currently caught up in what are known as "county lines" – meeting orders for heroin and cocaine via mobile phone "deal lines". They are transporting drugs from cities to rural and coastal towns, and carrying weapons too – knives, hammers and acid. Many find themselves selling drugs in a strange town, trapped, too scared to leave. Increasingly, when police raid the "traphouses" where the drugs are held, they are finding girls.
