Jonty Bravery, the man who threw a six-year-old boy from the 10th floor of the Tate Modern in 2019, has been found guilty of assaulting two nurses at Broadmoor Hospital. The 24-year-old, already serving a life sentence for the Tate Modern attack, was convicted in September 2024 of two counts of assault after an incident in which he “kicked one in the thigh and clawed at the face of a second,” leaving blood streaming down her cheek.
Bravery did not attend his trial at Westminster Magistrates’ Court. Prosecutor Tom Heslop described how Bravery is under constant supervision at Broadmoor, monitored by three staff members “24 hours a day, seven days a week” and kept in a room with only a mattress. The court heard that staff intervened after Bravery attempted to climb a ledge in the hospital room, risking self-harm. They placed him on his mattress and turned him onto his back before the assault occurred.
Body-worn footage shown in court captured the nurses struggling on the floor with Bravery until additional staff arrived to help. One panicked staff member is heard shouting, “Jesus Christ, do something.” Bravery reportedly “kicked out towards” Kate Mastalerz, hitting her thigh, and “clawed across” Linda McKinlay’s face, causing her injury.
Chief Magistrate Paul Goldspring described Bravery’s actions as having “gone too far” when delivering the guilty verdict on both charges. Sentencing has been adjourned until 8 January, with the court requesting an update on Bravery’s current mental health.
This latest conviction adds to Bravery’s history of violence in secure settings. In 2020, he received an additional 14-week sentence after admitting attacks on other Broadmoor staff. The case highlights ongoing concerns about managing high-risk individuals within high-security hospitals.
