A 50-year-old man from the village of Stanwell, near Heathrow Airport, was arrested Saturday on suspicion of attempted murder and racially aggravated public order offenses. A 19-year-old man was taken to the hospital with non-life-threatening injuries.
Neil Basu, head of counter-terrorism policing, said Sunday that while the investigation was just beginning, the incident had "hallmarks of a terror event." He added "police are committed to tackling all forms of toxic extremist ideology."
