The most senior family court judge in England has described the growing use of Deprivation of Liberty orders for vulnerable children as a 'crisis.' File on 4 hears from young people who were held under the order supposedly for their own safety. But they say they were under constant supervision, denied access to their phones and the internet and kept away from their families. Some say they were subjected to physical restraints and even supervised when they were having a shower. And one teenager who was on a Deprivation of Liberty order tells the programme he preferred being in prison.
