Hotel Custody

ITV, 9pm (not Scotland)

Cameras follow the work of police and detention officers at the Humberside Police custody facility, a state-of-the-art, £14m detention centre in Grimsby. It’s a crazy Halloween night with people dressed as the Joker and Harley Quinn checked in for assault. Plus, Gangsta Granny is looking forward to her ‘holiday’ in a cell, and a welcoming party is needed for a violent detainee. ★★★★★
