A masked arsonist has been caught on CCTV calmly pouring petrol around a bakery before sending a surge of flames shooting through the building.

Shocking CCTV footage has emerged showing a pair of thugs burst into a man's office before choking him unconscious and snatching a gold Rolex watch from his wrist.

Closed-circuit television (CCTV) footage of a man who entered a Bangkok temple shortly before a blast that killed 22 people could shed light on who was behind the unprecedented attack.
