A prisoner made his way onto the roof of HMP Strangeways in Manchester in a protest that lasted over nine hours
He has been named as 35-year-old Stuart Horner, who was jailed for murder in 2012 over the killing of his uncle.
Horner is understood to be protesting over conditions at the Manchester jail.
At around 5.30pm today, Sunday 13 September, he scaled an 18 foot metal fence before settling on the roof of the prison, wearing only a pair of blue and yellow pyjamas.
Riot police are at the scene and negotiating are underway with Horner.
He is reported to be singing and dancing on the roof.
Onlookers reported the 35-year-old to say his protest was over being locked up in his cell “for days”, “I’m doing this for everyone here”, complaining about overcrowding and being treated “like an animal”.
Police arrived on Southall Street at around 6.20pm tonight to find journalists at the scene, with crowds gathering outside the main walls.
For around two hours prisoners could be heard shouting, whilstling and cheering encouragement to Horner.
By 8.30pm he had scaled a metal pole with shouts from prisoners still ongoing as the sun went down.
Negotiations continued into the night, with Horner climbing to the roof of the infamous prison, wearing only a pair of Manchester United boxer shorts.
Fire crews arrived at the scene at around midnight, with plans to use an aerial platform to bring Horner back to ground level.
