One was fat, and the other, thin. Together, the robbers became richer with jewellery worth about RM300,000, in less than two minutes.

Earlier, the duo had struck at a goldsmith shop in Jalan Besar, Tanjong Malim south of here Wednesday, and escaped with the loot.

In the incident about 1pm, the robbers, one brandishing what appeared like a pistol, held up a 54-year-old worker at the shop.

Wearing full-faced helmets with tinted visor, they ordered the man to empty the loot into a sling bag before escaping in a motorcycle in the direction of Hulu Bernam.

Tanjung Malim police chief Supt Othman Nanyan said the shop neither had a security guard nor was fitted with a closed-circuit television camera.
