Acting Selangor police chief S Sasikala Devi said the victim and two suspects, aged 33 and 30, were acquaintances from their village in Kedah, with the husband being a contractor and his spouse a housewife.

However, Sasikala refused to comment if jealousy was an element in the case.

“Police have already taken statements from 36 witnesses to help in the investigation and so far no follow-up arrests have been made. The investigation against the couple is continuing.

“Police raided the couple’s house in Serdang, Kedah, on Thursday and seized several items connected to the case such as a paper cutter and firecrackers believed to have been used to make the explosive,” she said at a press conference here today.

The suspects were arrested on Wednesday under Section 302 of the Penal Code for murder.

Sasikala advised the public not to speculate on the case.
