At the time, a spokesperson for the Metropolitan Police said:
A man was seen outside the centre gate in possession of two knives.
He was not making threats to members of the public but he was challenged by police.
He acted aggressively and a Taser was discharged.
Nevertheless, the incorrect suggestion that this man was responsible for the Westminster Attack was made by Russia 24, appearing on their website, and later promoted on Facebook by Russia News 24's parent company Vesti.
Originally it was posted with the caption:
The London terrorist had a knife with a green handle in his hand.
FALSE image of London terror attack shared by Russian media.
The image reappeared alongside a later post, which debunked it.
According to a reporter for the Moscow Times, another Russian channel, "Channel 5," also used the false image.
The story and comments were made at approximately 7.44pm on Russia 24.
The image was not used in the 8pm broadcast that followed.
