The man behind the terror attacks was wrongly named as a former Leyton resident by media outlets.
According to an article since deleted by The Independent, 41-year-old Abu Izzadeen drove a car into the Houses of Parliament and attempted to attack police officers.
However, sources on Twitter say his solicitor claims he is still in jail, having been convicted for breaching counter terrorism restrictions
Channel 4 also named him as the attacker during a TV segment this evening. It has since published a statement saying: "On tonight's Channel 4 news, senior home affairs correspondent Simon Israel quoted a source as saying the name of the Westminster attacker was believed to be Abu Izzadeen, formerly known as Trevor Brooks.
"During the course of the programme, conflicting information came to light. We are currently looking into this."
One police officer died outside Parliament, while two others died after a car ploughed into Westminster Bridge.
Police say one of the men responsible for the attack is dead, but his identity remains unknown.
In 2008, Izzadeen lived at Brierley Road, Leytonstone. Izzadeen was born Trevor Brooks in Hackney, but converted to Islam aged 18 in 1993. He originally changed his name to Omar but preferred to be known by Abu.
