A convicted killer has been staging a protest on top of HM Prison Manchester for more than 24 hours. Stuart Horner, 35, scaled an 18ft fence to get on the roof of the high-security men's jail on Sunday afternoon, and refuses to come down.

Horner, who was sentenced to a minimum of 27 years after shooting his uncle dead in 2011, has claimed that he will stay on the roof for 40 days and 40 nights.

The inmate, who earlier stripped down to just his Manchester United underwear, has been climbing up chimneys, smashing windows and walking along the edge of the roof.

A spokesman for the local police force confirmed the protest: "The man is conducting a lone protest and has managed to get onto the top of the main building and cause damage to the roof."

Although it is unclear exactly why Horner is protesting, he has reportedly been shouting about prison conditions, and wrote a note on his t-shirt saying: "It's not 1990 tell the Gov we've all had enough. Sort the whole system."

A cherry picker was brought in on Monday, and all the roads around the prison have been sealed off, while riot officers keep a watchful eye on the scene.

HMP Manchester was known as HMP Strangeways, after the area in which it is located, until it was rebuilt and renamed in 1990 following a major riot in which two people died and hundreds more were injured.
