Manchester bomb plotter moved back to Belmarsh prison after guards attacked in jail in Durham

The Manchester Arena bomb plotter Hashem Abedi has been moved back to Belmarsh prison after an alleged attack at HMP Frankland on Saturday.

Three prison officers at the high-security jail in County Durham were attacked with cooking oil before being stabbed with an improvised weapon. Abedi has been transferred to Belmarsh prison in southeast London where he'd previously been found guilty of attacking a prison officer in 2020, along with two other convicted terrorists.

Belmarsh is considered the most high-security prison in the UK. Abedi has been moved to the only available highly-controlled 'suite' cell in the country - a standalone self-contained unit monitored by a minimum of five people at any one time, and a prison dog.

There are only four such cells across England and Wales. Abedi was convicted of assisting the Manchester terror plot, in which his brother Salman Abedi killed himself and 22 other people by detonating a bomb in a rucksack at an Ariana Grande concert in May 2017.

Hashem Abedi was sentenced in 2020 to at least 55 years in prison after being found guilty of 22 counts of murder over the atrocity. Meanwhile, the government has said it will commission a review into the incident at HMP Frankland, after suspending access to cooking facilities in separation units, which is where the alleged attack took place.

Sky News understands the Prison Officers Association, after visiting staff who were on duty at the category A jail this week, have written to Prime Minister Sir Keir Starmer calling for urgent action in order to protect prison staff in the high-security estate. The union wants to see prison officers working there given stab-proof vests, access to tasers in certain situations, and not just a suspension of self cooking facilities in separation units but a full ban.

Separation units house the country's most dangerous and violent criminals.

On Sunday, convicted killer John Mansfield was found dead at a category A prison, HMP Whitemoor, in Cambridgeshire. Police said they arrested a 44-year-old man on suspicion of murder.

Sky News also understands there was an incident on Tuesday lunchtime at HMP Lowdham Grange in Nottinghamshire. A specialist 'response group' consisting of officers from outside the prison were deployed to bring the situation under control, along with a 'hostage' situation, while prisoners climbed on the roof and netting.

The situation was brought under control within an hour. Prisons minister Lord Timpson said it was "another sign of the problems we are facing in our prison with prisons that are overcrowded and violent"..
