It's a game of comic and tragic survival for the police custody teams and the prisoners of the Lock Up. For a year a BBC team had exclusive access to the custody suite of Humberside Police that specialises in hosting Hull's 2,000 young people who are arrested annually.

The Lock Up is the place to sober up. Whether you are smashed, steaming or sozzled, alcohol plays a part in a million violent assaults countrywide every year. In the second part of the series, Sgt Rich West, policeman and Football League linesman, calls time on the prisoners who kick off.

When a fight breaks out after a wedding it gets fruity for the custody team as they get a frisking from a guest - a fresh first-timer and mother of two. The sergeant talks down a violent headbanger who gives himself a headache on the cell door. A teenage graffiti artist arrives smashed, and so is his mother's house after he has been on a drunken rampage. And an old regular is still standing after blowing five times over the limit, a level that could have have killed some people. Show less
