A knife-wielding man has killed one person and critically injured five others in a series of attacks across north London during morning rush hour.
Police arrested a man in connection with the stabbings.
They said the suspect, described as approximately 30 years old and of either Turkish or Middle Eastern appearance, had driven in a car to at least five different locations to stage the attacks.
"We believe these incidents are linked," police said in a statement. "A man has been arrested in Haringey borough in connection with the stabbings."
One stabbing happened near the Green Lanes train station, another in Ecclesbourne Gardens and another in Meridian Way.
