Detectives investigating the murder of a prisoner at the high-security Belmarsh prison have named the victim, but are still searching for a motive.

Sundeep Ghuman, 36, was found with head injuries on Tuesday, February 18 following an assault with the prison facility.

Police were called around 8pm, and took Mr Ghuman to hospital in critical condition where he later died on the evening of Wednesday, February 19.

Two men, both inmates at HMP Belmarsh, were arrested at the scene on suspicion of attempted murder.

A post-mortem of the victim took place at Greenwich Mortuary on February 21, giving the cause of the death as a head injury. His enxt of kin are aware.

The suspects, both aged 28, have been bailed pending further enquiries.

Enquiries into the circumstances continue, led by the Met’s Specialist Crime Command under Detective Chief Inspector Richard Leonard.

DCI Leonard, said that at this stage he was "open minded concerning motive," but added that he expects this to become clear as the murder investigation progresses.

"We are working to establish the circumstances surrounding this incident with the support of the prison and local officers."

Belmarsh in south-east London is one of only three high-security "core" local prisons in England and Wales. It has housed some of Britain's most high-profile prisoners.

An inspection report in 2018 showed that levels of violence had increased at Belmarsh since it was last assessed three years previously.
