Selangor Police CID chief Mohd Adnan Abdullah said the four suspects, aged between 31 and 40, were arrested in an apartment in Ampang about 1am on Saturday.

“In the raid, police also seized a BMW car bearing fake registration numbers, some tools for break-ins and global positioning system (GPS) trackers,” he said in a press conference here, today.

Mohd Adnan said they did not rule out the possibility that the bombs were used in burglary and illegal moneylending activities.

“However, we are still investigating to what extent the handmade bombs were used in their criminal activities.

“The suspects are being remanded until tomorrow and the case is being investigated under the Explosives Act 1957,” he said.

On April 17, more than 200 Damansara Perdana residents were shocked after seven “hand grenades” were found in one of the condominium units about 4.30am.

Police also found electronic equipment, drugs believed to be methamphetamine weighing 2kg and a number of Eramin 5 pills.
