A scream was heard, and a young male was tasered before being arrested and led away by police officers. Among the four officers immediately on the scene were two armed men from the protection squad patrolling the palace and two ordinary constables, one carrying a baton.

Scotland Yard, the headquarters of London policing, released a statement confirming the basic facts of the event without giving any further detail.

The man was bundled to the cobbles just inside Carriage Gates, not far from where Westminster terror attack Khalid Masood murdered PC Keith Palmer last year, just before midday today.

The suspect made it a few metres into the Parliamentary estate before he was stopped and Tasered to the ground.

He was reportedly heard shouting 'coming for you politicians' before he was put in a police van and driven away.

It is understood the incident is not currently being treated as terror-related.

One witness told The Independent: 'I heard police shouting – at first I thought they were just shouting at tourists to stay back – but there was a guy stood just inside the gates facing [away from Parliament].

'He was just stood there with his arms out being approached by lots of police and wasn't responding to the screams. I heard a crack, which I guess was the Taser because I saw the Taser wires after, and he went down and very quickly they were all on him.'

Pictures from the scene show the man - who was wearing a black cap, a green jacket and jeans - pinned to the ground with three officers around him.

One of the policemen was aiming a gun at his head, another had used the Taser and a third held a baton.

Another eyewitness said: 'I saw a guy fall to the floor and he was on the floor surrounded by armed officers. He was shouting something.

'He had been Tasered, you could see the wires. I did not hear the police shouting anything, but that could be because of all the commotion.

'They handcuffed him and got him to his feet, then unzipped his jacket to see if he had anything hidden on him

'Everybody was just watching, surprised that something like this was happening. Two armed police cars, BMW X5s turned up and armed police came out of the grounds and told us to get back. They then set up cordons around the entrance.'
