The suspect, a Sudan-born British national, has been identified by a European security source, Reuters reports. It added he was not known to intelligence services before Tuesday.
The man was also identified as Khater by governmental sources, according to the BBC. RT approached the police to verify the reports, but this could not be confirmed.
Khater has been arrested on suspicion of ramming a car into pedestrians and cyclists before crashing into security barriers outside the Houses of Parliament. The suspect is being held in custody in south London, and is said to be not cooperating with police.
Scotland Yard’s head of counter-terrorism Neil Basu said no other suspects have been identified.
Police are searching three properties as part of their investigation into the incident – two in Birmingham and one in Nottingham.

It is the second terrorist attack on the Houses of Parliament in just under 18 months. The first one in March last year claimed the lives of five people, including a police officer.
In a third incident, an attempted attack was foiled when counter-terrorist officers arrested the potential assailant, who was found outside parliament in possession of three knives.
Three people were treated at the scene of Tuesday’s attack. Two were taken to hospital. A man suffered “non-serious” injuries and a woman sustained “serious, but not life-threatening injuries.” Both have been discharged from hospital.
Basu, who is leading the investigation, said there is nothing to suggest that the public are in danger but nonetheless called on them to remain “vigilant.”
