The probe into the past of the Westminster terrorist continues as Scotland Yard reveal what they believe to be his birth name.
Mark Rowley, the Metropolitan Police's Assistant Commissioner, has said they believe Khalid Masood was known as Adrian Russell Ajao prior to his conversion to Islam.
The investigation has reportedly revealed the middle-aged man had many aliases, and it's been confirmed he had a string of previous convictions after he was unmasked as the culprit behind Wednesday's terror attack.
The Sun is reporting he stayed in a hotel in Brighton, the Preston Park Hotel, hours before committing the atrocity.
The paper claims police officers were seen investigating the hotel and the room he stayed in after finding a receipt for the hotel in the car he used to attack pedestrians on Westminster Bridge.
The hotel staff have reportedly been instructed to issue no comment over the investigation.
Masood killed three people by driving his car into pedestrians on Westminster Bridge, before fatally stabbing PC Keith Palmer on the grounds of the Palace of Westminster.
He was later shot dead by armed police shortly after his attack on PC Palmer.
Eight people are still in police custody after overnight raids on six properties in connection with the attack across London and Birmingham.
