At about 13:20hrs on Wednesday 21st June 2023 a lone male entered the Central Middlesex Hospital in Park Royal London allegedly carrying a Mattock (a type of small pick axe) and caused life changing injuries to one person and serious injuries to a second.  Since the incident occurred the police have confirmed that they are not looking for anyone else in connection with the incident and they are not currently treating it as a terror attack. The Hospital reopened at around 16:00hrs on the same day but services were interrupted.

While armed police entered the hospital site the hospital themselves implemented their lockdown procedure and began to evacuate patients and visitors whilst others gathered in offices and locked themselves in for safety.

The police have released a statement, providing details that one man has been arrested at the scene and had sustained “self-inflicted” injuries with London Ambulance confirming they have treated three people at the scene.

Matteo Bottarelli, 43, of Central Way, Park Royal, remains in police custody and has been charged with these offences – he appeared in court on Wednesday 21st June 2023.
