A man reported to have a firearm who was shot dead by officers was carrying a knife, police confirmed.
Officers were called to Milton Keynes Central at 12:55 BST on Tuesday where they initially said they challenged a suspect carrying a firearm, before a shot was fired.
A Thames Valley Police (TVP) spokesperson said “life-saving actions” had been taken but the man was pronounced dead at 13:44.
The force later said officers had challenged a man who actually had a knife and who had “moved at speed towards officers” with it.
