CCTV footage has shown the moment a thug tried to carjack police officers - armed with a supposed 'gun' that was actually made from a Primark brown paper bag.

Matthew Sylvester, 37, was caught on camera chasing a police car while pointing the imitation firearm in Telford, Shropshire, on February 22, a court has been told.

Officers had been called after Sylvester tried to smash his way into a shop with a shopping trolley before indecently exposing himself to staff cashing up inside.

Shrewsbury Crown Court heard he then wrapped a jumper around his face and fashioned a gun from a brown Primark bag after learning police were on their way.

After spotting the patrol car enter the car park through the barrier, he immediately charged at the vehicle while brandishing his makeshift weapon.
