Porteus

The Lock-Up returns for its second series on BBC One offering a powerful and honest account of life inside the custody suite at the headquarters of Humberside Police. Each film focuses on an individual custody sergeant, the man in charge of each shift and responsible for the wellbeing of up to 15 detainees and a team of detention officers.

Sgt Dave Porteus comes to the rescue of a young woman, banged up for burglary, who tries to kill herself by shoving toilet paper down her throat. And when she's on the mend, two more detainees decide that spitting is an acceptable form of greeting. Needless to say, Sgt Porteus disagrees.
