KUALA LUMPUR: Police seized 1.4kg of heroin worth RM120,000 and arrested a suspected drug trafficker who was in an express bus on Jalan Duta here.

Following a tip off, police personnel from the Kuala Lumpur Narcotic Crime Investigation Division (NCID) stopped the bus to detain the 26-year-old man at about 8.20pm last Saturday (Sept 1).

City NCID chief Asst Comm Adnan Azizon said police also searched the suspect's duffle bag and found six packets filled with heroin.

He estimated that the drugs seized could have supplied 2,950 addicts.

"We are investigating further to uncover the suspect's drug trafficking network," he said in a statement, adding that police would always be vigilant against the drug menace in the city.
