A man who stabbed a teenager in a supermarket car park in what police said was a terrorist incident has pleaded guilty to attempted murder.

Vincent Fuller, 50, was arrested after stabbing a 19-year-old Bulgarian man in a Tesco car park in Stanwell, Surrey, on March 16.

The victim was treated in hospital after suffering injuries to his hands and neck in the attack.

Surrey Police said at around 11pm, Fuller approached a vehicle in the car park and stabbed the driver with a knife through an open window.

He fled the scene but was arrested by armed officers shortly afterwards, and police declared it a terrorist incident the following day, with Counter Terrorism Policing South East leading the investigation.

Fuller, of Viola Avenue, Stanwell, appeared at Kingston Crown Court on Friday.

He admitted attempted murder, carrying a weapon, affray and racially aggravated harassment, alarm or distress, and will be sentenced at Kingston Crown Court on September 5.

The attack happened the day after a terror attack on two mosques in Christchurch, New Zealand, that left 50 people dead, and officers were called to reports of a man acting aggressively and shouting racist comments while carrying weapons in Viola Avenue, where vehicles had been damaged.

One witness said at the time that Fuller had been heard shouting "kill a Muslim" and "white supremacy", while another said he was "saying some crazy things about Muslims".

Assistant Commissioner Neil Basu, head of counter-terrorism policing, said of the incident at the time: "It has hallmarks of a terror event, inspired by the far right, and therefore it has been declared a terrorism incident."

Then prime minister Theresa May tweeted: "My thanks to the emergency services for their handling of the terrorist incident in Stanwell. My thoughts are with the injured man, and his family and friends. Vile, hateful far-right extremism has no place in our society."
