Scotland Yard said life support to the unidentified man was withdrawn, and added that five remained in a critical condition in London hospitals, while one person had life-threatening injuries.

The other four dead in the attack have been identified as: Khalid Masood; police officer Keith Palmer; Kurt Cochran, 52, from Utah in US, and teacher Aysha Frade.

Scotland Yard said detectives were continuing to search a number of addresses linked to the attack -- three in Birmingham and one in east London. Searches were also conducted in Carmarthenshire, Brighton and south east London.

Eight people arrested from six locations included three women and five men on suspicion of preparation of terrorist acts.

The police said, “After the fatal shooting of Khalid Masood by a police firearms officer, as is required, a referral was made to the Independent Police Complaints Commission. The investigation by the Counter Terrorism Command into the terrorist attack on Wednesday continues to develop at a fast pace and involves hundreds of detectives”.
