Second man held over Buckingham Palace knife terror incident

The unnamed 30-year-old was seized at a West London address on suspicion of being involved in the commission, preparation or instigation of terrorism. A 26-year-old man from Luton was arrested outside Buckingham Palace late on Friday after he drove at police before lunging for a 4ft sword and repeatedly shouting "Allahu Akbar".

The man was wrestled to the ground by unarmed police who had to use CS gas to incapacitate him.

During the struggle three officers were injured, two of whom suffered minor cuts to their hands and required treatment in hospital before being discharged.

The attacker is also being held under terrorism legislation and a warrant for his further detention has been granted. Scotland Yard initially said they were not seeking anyone else in connection with the attack. Commander Dean Haydon, of the Met's counter-terrorism branch, said: "A blue Toyota Prius deliberately drove at a marked police vehicle and stopped in front of it.

"Uniformed officers then confronted the driver of the vehicle and during that confrontation the driver reached for a four-foot sword that was in the passenger footwell.

"CS gas was used as part of the arrest and during the struggle the individual repeatedly shouted the words Allahu Akbar." He praised the "bravery and professionalism" of the officers.
