BBCAn 11-year-old girl and 34-year-old woman have been stabbed in London’s Leicester Square.
In a post on X, the Met Police said a man had been arrested and taken into custody, adding the force does not believe there are “any outstanding suspects”.
Paramedics said the two victims had been taken to “a major trauma centre”. Their condition is currently unknown, according to the Met.
Police officers remain at the scene, which is in one of the busiest tourist districts in the capital.
A London Ambulance Service spokesperson said paramedics were called at 11:36 BST to reports of a stabbing.
They said: “We sent resources to the scene, including an ambulance crew, an advanced paramedic and an incident response officer. We also dispatched members of our tactical response unit.
“We treated a child and an adult at the scene and took them to a major trauma centre.”
Soon after the attack, several police officers were still at the scene next to the Lego store on Swiss Court, just off the square itself.
Objects could be seen on the ground behind crime scene tape, with a small crowd of people gathered in the distance.
