KUALA LUMPUR: More than 100 gamblers were caught off-guard as police raided a cock-fighting ring located in a forested area in Melwood Arena, Sungai Buloh.

It is learnt that illegal gambling has been going on there for about eight months.

Based on surveillance and intelligence gathering since October, a team of Bukit Aman CID’s Anti-vice, gambling and secret societies division (D7) officers raided the gambling den on Sunday in an operation codenamed “Ops Dadu Mega”.
