An Uber driver terror suspect arrested outside Buckingham Palace had originally headed for Windsor Castle but his SatNav sent him to a pub of the same name instead.

Mohiussunnath Chowdhury, 26, was taken into custody after allegedly driving a blue Toyota Prius at a marked police car outside the Palace last Friday.

Police said the suspect reached for a 4ft-long samurai sword and yelled "Allahu Akbar" as he was tackled by officers and sprayed with CS gas.
