KUALA LUMPUR (THE STAR/ASIA NEWS NETWORK) - A 35-year-old Malaysian politician, who is believed to produce his own mixture of drugs and sell it at RM300 (S$98) a bottle, has been arrested.

The man, who had contested for a post in a party's Youth wing, was arrested in Pudu at 1.45pm on Wednesday (Jan 20).
