Mr Gosling, 70, was held by police within 36 hours of confessing to smothering his partner with a pillow as he lay dying of Aids in hospital.
Officers arrested him at his home in sheltered accommodation in Nottingham yesterday morning. He was still being questioned at Oxclose Lane station last night.
On Monday, the broadcaster used a documentary on BBC East Midlands’ Inside Out programme to claim he made a pact with an unnamed partner – who he later described as his ‘bit on the side’ – to end his life if the pain got too severe.
He told Radio Four’s Today programme that he did not fear police action, adding: ‘I don’t do worry – bugger the law.’
He insisted he would not tell police the name, place or date of the killing, which happened ‘a long time ago’. Read in full at the Daily Mail.
