PETALING JAYA - The police are on the lookout for those who regularly surf the Internet for militant and bomb-making websites.
Bukit Aman's Special Branch Counter Terrorism Division principal assistant director Senior Asst Comm Datuk Ayob Khan called on the public to tip off the police about any colleague or family member who has a "particular fondness" for such websites.
On the increasing number of homemade bombs detected in the country, he said that since 2012, there were 39 such cases most of which were related to business rivalry and personal vendettas.
None is linked to terrorism so far.
"Regardless, we want to nip this in the bud," said Ayob.
Ayob reminded chemical suppliers and hardware stores to alert the police if there were large quantity purchases of dangerous items like ammonium nitrate fertilisers by suspicious characters.
Under the Explosives Act 1957, those making or possessing explosives can be jailed seven years or fined RM10,000 (S$3,917) or both, he warned.
Senior professor of Inorganic Chemistry at Universiti Kebangsaan Malaysia Prof Dr Yang Farina Abdul Aziz said ammonium nitrate, which is widely used as a fertiliser, is an easily available explosive compound.
"That is why we have to ensure we keep a registry of who is buying fertiliser. Mixed with any household product that contains potassium chloride and you will have potassium nitrate on your hands - an explosive concoction that is basis for bombs," she cautioned.
Malaysian Chemistry Department forensic division director Dr Kamaruddin Asri warned that even household items like corrosive cleaning detergent can be dangerous "if you have a criminal mind".
"Once you have the intention, the knowledge is easily available on the Internet.
"That is the problem with a borderless world - everything is easily accessible," he said, warning that chemicals should never be handled by non-competent personnel as the damage could be great.
