1. The Prisons and Probation Ombudsman aims to make a significant contribution to
safer, fairer custody and community supervision. One of the most important ways in
which we work towards that aim is by carrying out independent investigations into
deaths, due to any cause, of prisoners, young people in detention, residents of
approved premises and detainees in immigration centres.
2. If my office is to best assist His Majesty’s Prison and Probation Service (HMPPS) in
ensuring the standard of care received by those within service remit is appropriate,
our recommendations should be focused, evidenced and viable. This is especially
the case if there is evidence of systemic failure.
3. In May 2011, Mr Bryn Tomaz-Daniels (formerly known as Brian Maddock) was
sentenced to life in prison for murder. He died in a hospice of lung cancer on 5
February 2025, while a prisoner at HMP Warren Hill. He was 54 years old. We offer
our condolences to those who knew him.
4. The prison was unable to trace a next of kin for Mr Tomaz-Daniels so the
Ombudsman’s office did not contact anyone about the investigation into his death.
5. NHS England commissioned an independent clinical reviewer to review Mr Tomaz-
Daniels’ clinical care at Warren Hill.
6. The clinical reviewer concluded that the clinical care Mr Tomaz-Daniels received at
Warren Hill was of a good standard and equivalent to that which he could have
expected to receive in the community. He made no recommendations.
7. The PPO investigator investigated the non-clinical issues relating to Mr Tomaz-
Daniels’ care.
8. We did not find any non-clinical issues of concern. We make no recommendations.
9. We shared our initial report with HMPPS and the prison’s healthcare provider,
Practice Plus Group. They found no factual inaccuracies.
