Police in New York City are looking for a quick-thinking thief who stole a bucket of gold flakes worth nearly US$1.6 million off an armoured truck in Manhattan.

The federal ministry of labour has ordered Brink's Canada Limited to change its practice relating to the driver and guard both exiting the armoured vehicle at drop-offs and pick-ups, saying it puts workers in danger.

Cellphone video captured the moments after the door of a Brinks armoured car opened while driving on a Texas interstate, spilling cash all over the highway.
