Two more "significant" arrests have been made in the Westminster terror attack investigation, and the fourth victim of the attack has been named.
Today's arrests were made in the west Midlands and the north west, police said.
The man who carried out the attack, who was shot at the scene, was yesterday named as Khalid Masood, a 52-year-old who was born in Darftord, Kent. Met Police assistant commissioner Mark Rowley today confirmed his birth name was Adrian Russell Ajao.
"Masood was not the subject of any current investigations and there was no prior intelligence about his intent to mount a terrorist attack," the police said.
"However, he was known to police and has a range of previous convictions for assaults, including GBH, possession of offensive weapons and public order offences.
"His first conviction was in November 1983 for criminal damage and his last conviction was in December 2003 for possession of a knife.
"He has not been convicted for any terrorism offences."
