'Mostly, it's lonely': Teenager describes reality of being held almost 24 hours a day in solitary confinement

Seventeen-year-old Kyefer spends 23-and-a-half hours a day between the four walls of a small cell. In the room is a bed, a shower and a desk. He lies on his bed and does nothing.A meal is delivered three times a day through a slot in the door, which he eats alone. He has no television, and only a few books to keep himself occupied. Since he was referred to Cookham Wood Offenders Institution's Segregation Unit several months ago, the teenager has been receiving no form of regular education.The only stint of daily exercise he gets in the Kent jail is at around 8:30am, when inmates on his wing are allowed half an hour outside.
