A suspected knifeman was tasered by armed police near the Houses of Parliament this morning after “behaving erratically”.
Video shared online shows at least six officers surrounding an individual on the ground.
Police said he was arrested on suspicion of possession of a bladed article. He has since been taken into custody.
No one was reported to have been injured.
The road near the Houses of Parliament in Millbank appears to have been shut in one direction as pedestrians walk by.
A Metropolitan Police spokesperson told The Mirror: “At around 11:50hrs on Friday, 21 October a man was seen behaving erratically in the SW1 area.
“He was stopped by armed officers on Millbank.
“Police taser was discharged and the man was arrested on suspicion of possession of a bladed article. He has been taken into custody.
“There have been no reports of any injuries.”
Earlier this week, a suspicious package was found near Downing Street causing police to close Whitehall.
Civil servants including from the Treasury have been evacuated, with hundreds were seen waiting near Horse Guards Parade round the back of Whitehall and Downing Street.
A stretch of Whitehall a few hundred metres long was shut with “police do not cross” tape.
The section that was closed to all vehicles and pedestrians, stretches from Parliament Square past Downing Street and the Cenotaph.
Officers were seen standing guard at the cordons with a small number of police vehicles inside the taped off area.
The Met Police said on Twitter: “Police were called at 11.42hrs on Tuesday, 18 October to reports of a suspicious package in Whitehall.
“Officers are in attendance and a cordon is in place as a precaution.
“The item will be assessed by specialist officers. Please avoid the area.”
A government official said some of the government buildings along Whitehall had been emptied.
Police later added the item was declared “non-suspicious”..
