Police on Sunday found five homemade bombs in a condominium unit in the outskirts of the Malaysian capital, forcing the evacuation of about 200 residents, an official said.
Bomb-making equipment, including a coal powder and several pipes and wires, were also seized during a raid on the 17th floor of the block in Damansara Perdana in Petaling Jaya, according to police chief Mohamad Zani Che Din.
Two suspects escaped, Mohamad Zani said, adding the bombs were safely detonated at a nearby quarry.
Aside from the bombs, police officers also seized illegal drugs in the unit, he added.
Police have remained on heightened alert throughout Malaysia following January bombings in the Indonesian capital Jakarta that killed several people.
