A 47-year-old woman has been arrested after four men were stabbed in Covent Garden in central London, the Metropolitan Police said.
The men, aged 34, 39, 42 and 52, were taken to hospital after emergency services were called to reports of a stabbing in Endell Street at about 12:30 BST.
The force said two men remain in hospital with injuries not thought to be life threatening or life changing while the other two have been discharged.
The woman was arrested on suspicion of possession of an offensive weapon and assault. The Met said it was believed to have been a mental health-related incident.
Ch Supt Jason Stewart said: “Officers responded within minutes of this incident after receiving a number of reports.
“While still at an early stage of the investigation, we would like to reassure the community that we currently believe this to be an isolated, mental-health related incident.”
He added a “visible police presence” would remain in the area while evidence was gathered.
