Dramatic footage has shown the moment a knife-wielding man accused of plotting a terror attack was taken down by armed police near parliament.

Khalid Ali, 28, was arrested at the Parliament Street junction in April last year, four weeks after Khalid Masood killed five people in the Westminster Bridge attack..

Bodycam: Terror suspect on ground as police make knife arrest

Video of Ali's arrest was played at the Old Bailey where he is on trial accused of preparing acts of terrorism.

The body-worn camera footage shows him on the pavement when he was surrounded by armed officers.

Ali is then seen on the ground as an officer asks him if he has anything on him that would cause harm.


The defendant replies: "You'll see."

He is seen bleeding from a cut on his hand as an officer wearing forensic gloves searched his pockets and clothes.

After an officer uncovered three knives, Ali was further arrested for having a bladed article.

In the footage, an officer tells his colleagues: "Let's make absolutely sure he has not got anything else before we put him in the car."

Other officers seized the knives on the ground as Ali was led away in handcuffs.

While in custody, Ali's clothes were taken away and he was found to have a small cut in the front of his underwear where the largest of the three knives was found, jurors heard.

His DNA was on all three blades, prosecutor Alison Morgan said.

Ali allegedly armed himself that day to deliver a "message" to British decision-makers.

The court has heard he planned an attack in the UK after spending five years making bombs with the Taliban in Afghanistan.

He carried out "hostile reconnaissance" around Downing Street, New Scotland Yard, the Ministry of Defence, the MI6 building and the Cenotaph on 18 March and 22 April last year, jurors have been told.

The prosecution alleges Ali was targeting MPs, police and members of the armed forces.

Ali, a plumber from Edmonton, north London, denies two charges of possessing explosives with intent abroad in 2012 and one charge of preparing terrorist acts in Britain.

The trial continues.
