“On six occasions he was found with a mobile phone in his possession,” the report said.
In September 2023 Digweed tested positive for cocaine and during this time he “harmed himself by making superficial cuts to his chest”.
He was offered support, which he declined, the report said.
On 27 September, staff removed Digweed’s prison laptop after they noticed he had damaged the screen.
He was without a laptop for six months which “impacted on his ability to control aspects of his daily prison life and might have negatively impacted his mental health and ability to maintain family ties”.
His telephone calls from this period also indicated that his relationship with his partner was “under strain,” the ombudsman said.
On 1 November, CCTV showed four prisoners enter Digweed’s cell and he was later found to have “injuries consistent with him being slashed with a blade”.
He claimed he had fallen but Digweed’s security file “indicated that the incident was thought to be drug debt and gang related”, the ombudsman said.
Digweed was last seen alive during a routine count of prisoners on the evening of 12 April 2024.
His observation panel was covered during the early morning routine roll check the following day and was still covered at a welfare check at 09:07 BST.
