Prison officers have been accused of corruption after shocking footage showed them turning a blind eye to drug use behind bars.
The video, taken on a phone a lag had smuggled into his cell, shows an officer confronting a prisoner as he stands outside their door - confronted with the stench of marijuana.
And when the convict pushes back - asking the officer openly what his room smells like - he is met with an extraordinary response as he is told to open his window so it isn't as obvious.
It comes as the prison service is in crisis, with out-of-control officers becoming notorious as stories of corruption and sordid relationships with their convicts hit the national headlines.
In the footage, obtained by Channel 4's UK Prisons - Sex, Drugs & Corruption: UNTOLD, the officer says: 'What the f*** is in that? I don't wanna know.'
