Contrary to an initial report of five bombs, there were actually seven homemade bombs found by the police at the Metropolitan Square Condominium in Damansara Perdana, reported Astro Awani.
The bombs were moved to a nearby quarry and safely detonated.
Said to be improvised explosive devices, the homemade bombs were made with PVC pipes and some of them had circuit boards
According to ACP Mohd Zani, the unit in which the bombs were found was rented. During the police raid two suspects, both locals, fled and are still at large.
It was reported that police also found syabu and ecstasy pills in the apartment.
Malaysiakini later reported that police also found about 10kg of narcotics in a car belonging to one of the tenants of the apartment. It quoted Petaling Jaya district police chief Zani Che Din saying that about "9kg of the narcotics recovered are believed to be ketamine. The remaining one kilogramme is believed to be cocaine."
While the Fire and Rescue Department personnel left the scene at 11.40am, the residents, some 200 of them who were evacuated from their condominiums around 8am, were finally allowed to return to their homes after the area was declared safe at about 12.30pm
A SAYS employee who lives in the same condominium where the bombs were found, said it was chaos in the morning
The police have ruled out the involvement of terrorists or militants. The Malay Mail reported that Bukit Aman Special Branch Counter Terrorism Division director SAC Ayub Khan Mydin Pitchay believes that gangsters were behind the manufacturing of the explosives.
The case is being investigated under the Explosives Act 1957.
Deputy Prime Minister Ahmad Zahid Hamidi, speaking about the incident, said that the national security is "completely under control" as this was not linked to the Islamic State (IS) terror group
"National security is completely under control, and while police have yet to establish a motive, we have traced a few possibilities, none of which are linked to the IS. This was caused by the actions of certain individuals," The Star Online quoted him as saying.
Added that police raided the condominium unit based on complaints claiming that illegal activities were taking place there, he said, "Police investigations will continue. I guarantee the public, especially the residents of that apartment, that police are always prepared to handle matters of security."
