Tim Cook defends Apple's removal of Hong Kong mapping app

Apple chief said in a letter HKmap.live was 'used maliciously to target' officers as claim was disputed by protesters on the ground

Tim Cook has written to Apple employees defending the company's decision to remove an app used by Hong Kong protesters to coordinate movements and avoid concentrations of police.

But the chief executive has been criticised for "taking at face value" the claims of the Hong Kong police, which don't chime with the experiences of international observers on the ground.
