Several media outlets reported that the identity of the UK House of Parliament attacker as Abu Izzadeen - also known as Trevor Brooks - a hate preacher of Jamaican origins.
The outlets reported the above information with pictures of the suspected attacker.
However, several reports have pointed out that Abu Izzadeen is in jail serving a two-year sentance since last January.
Channel 4 were one of the outlets to have misreported the identity of the attacker on Wednesday. They later retracted the claim in a statement released on Twitter.
