A paedophile who created a "hidey hole" to conceal one of his victims has been jailed for 27 years.
Michael Dunn abused four girls over a period of decades. He also knocked through the wall behind his fridge to hide one of his victims from police.
She was hidden from police around eight or nine times, as he used a bag of dust and a panel to cover the hole where she was kept, the BBC said.
He has been convicted of 10 rapes, three charges of indecent assault and three charges of false imprisonment. One of the girls he abused was just 10 or 11 when he first raped her.
A second female victim whom he imprisoned was also subjected to repeated violence and the house had many locks, cameras and alarms, Teesside Crown Court heard.
Prosecutors said victims "suffered physically" if they challenged him and "he had sex when he wanted".
Dunn is from Redcar, however his attacks took place in several places, including Manchester.
Greater Manchester Police has now referred itself to the Independent Police Complaints Commission over concerns about missed opportunities to catch Dunn.
