A man has been arrested and is currently in police custody following a stabbing at Central Middlesex Hospital yesterday.
The incident occurred after reports of two people being stabbed, prompting armed officers to respond.
Two men in their 40s were found with stab injuries, believed to have been caused by a mattock.
While the injuries are not considered life-threatening for one victim, the other may experience life-changing consequences.
The arrested man, also in his 40s, was found outside the hospital and was initially suspected of two counts of attempted murder.
He sustained self-inflicted injuries but they were determined to be non-life-threatening.
The man has since been discharged from the hospital and faces additional charges of possession of an offensive weapon, affray, and a third count of attempted murder.
The incident is not being treated as terror-related.
Detective Superintendent Will Lexton-Jones, acting commander for policing in Brent, said: “This is a shocking incident that of course will have been incredibly distressing for hospital staff, and those attending and visiting others.
“Our NHS colleagues acted quickly, and with incredible courage, to report the incident and lock the hospital down to ensure the safety of their patients. Our officers – armed and unarmed – responded within minutes and entered the building without a second thought for their own safety, not knowing at the time exactly what they were dealing with.
”I am enormously proud of everyone who responded to this incident. Once again, we see police officers running towards danger to keep the public safe. I also want to commend the detectives who deployed as soon as possible to secure the evidence and continue to work around the clock to deliver justice for the victims.
“While our enquiries are ongoing, I can say that both the suspect and victims are contracted hospital staff who are known to each other. We are satisfied that no one else is sought in connection, there were no reported injuries to any patients or visitors.
“We continue to establish exactly what happened and any witnesses are urged to come forward.”
Pippa Nightingale, Chief Executive of London North West University Healthcare NHS Trust, said: “I would like to express my sincere thanks to our colleagues for keeping our patients and staff safe, especially those members of staff who were first at the scene of the incident.
“Their professionalism is to be applauded along with the Metropolitan Police, the London Ambulance Service and all other agencies who have supported the Trust throughout the incident.”
