Scotland Yard said Masood was not the subject of any current investigations and there was no prior intelligence about his intent to mount a terrorist attack.
However, he was known to police and had 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 had not been convicted for any terrorism offences.
Anyone with any information about Masood can call the anti-terrorist hotline 0800 789 321.
