In 2026, the Offender Database recorded that Andrew Siberry, 61, died in custody at HMP Leeds from heart disease while being held on remand for repeat sexual offences and harassment. A Prisons and Probation Ombudsman (PPO) report published in January 2026 confirmed that Siberry, a former architect for Leeds City Council, died from coronary artery atheroma on June 2, 2025. It was reported that Siberry—of Newfield Crescent, Garforth—was awaiting trial for exposure and multiple breaches of a restraining order that required him to remain clothed in public and banned him from local businesses.
The investigation established that Siberry had a long history of predatory and anti-social conduct in the Garforth area. West Yorkshire Police reported that in 2020, he was jailed after being found in bushes near Barley Hill Road play park with his trousers down in view of children. The prosecution reported that Siberry frequently targeted staff and customers at the Tesco Express on Long Meadow Gate, where he would verbally abuse workers, urinate outside the shop, and expose himself to passersby. The investigation established that his behaviour included masturbating in public near residential ginnels and physically assaulting a shop worker at Fairburn Convenience Store.
Judicial Findings and Investigative Detail
The court reported that Siberry was subject to a five-year restraining order aimed at curbing his habitual public exposure. Leeds Crown Court heard in February 2024 that Siberry was jailed for 19 months after failing to comply with community orders and continuing to harass the public in Garforth. The investigation established that while held at Armley prison, Siberry engaged in persistent dirty protests, smearing his cell with waste and refusing to clean himself, which previously resulted in hospitalisation for potential sepsis.
The PPO report noted that Siberry was seen alive by a prison officer just ten minutes before he was found unresponsive. For his actions in Leeds, Siberry had been classified as a high-risk habitual offender whose conduct caused significant distress to the community, particularly women and children. The judge noted during his 2024 sentencing that Siberry’s refusal to modify his behaviour necessitated immediate custody to protect the residents of Garforth from his repeated acts of outraging public decency.

Monitoring and Public Protection
Prior to his death, Siberry was managed under Multi-Agency Public Protection Arrangements (MAPPA) within the Leeds area. Due to the nature of his conduct in Garforth, which involved the persistent targeting of public spaces and retail staff, he was a priority for the Public Protection Unit. Authorities state that Siberry’s history of public masturbation and exposure near play parks required the use of restrictive court orders to manage the risk he posed to children and the wider community.
As a registered sex offender, Siberry was subject to strict notification requirements until his death in HMP Leeds. Authorities state that his background as a council architect contrasted sharply with his subsequent pattern of “unclean” protests and public sexual offences. The PPO investigation concluded that despite his self-neglect and the conditions within his cell, the clinical care provided to Siberry met the standards expected in the community. His criminal history remains on record in West Yorkshire to ensure a complete account of the risks he posed during his residency in the region.
