PETALING JAYA - Police and the armed forces are trying to get to the bottom of how an ex-serviceman got his hands on a hand grenade.
The 50-year-old suspect is alleged to have used the explosive as a booby trap on his wife, who had been unfaithful to him.
The booby trap, however, ended up exploding underneath the car of another woman, who managed to walk away without sustaining any injuries.
Sungai Buloh OCPD Supt Junaidi Bujang said it is believed that the suspect used one of four types of military-grade grenades that produced minor blasts.
"They were meant to maim a person rather than destroy. But given the incident that took place, such an explosion could have been fatal," he said, adding that the type of explosive used in Saturday's incident was still being investigated.
Supt Junaidi said investigators were now working with the army to ascertain if the suspect may have obtained the explosive from accomplices within the military or during his time as an officer in the late 1980s.
The man was arrested at his home in Cheras and is being remanded until Friday.
While he could face up to seven years in prison, a RM10,000 fine or both, if found guilty under Section 6 of the Explosives Act, Supt Junaidi said the penalties could be heavier if police decided to submit a charge for attempted murder.
The suspect had allegedly planted the hand grenade at the end of a dirt driveway of a house in Kampung Baru Subang.
The booby trap was made by using a rock that kept the grenade pin down. When the pin was released or depressed, it would trigger an explosion.
The grenade exploded when a car driven by the woman dislodged the rock sitting on it.
The blast damaged the rear portion of her car but did not cause any injury.
