Zaky Pawas, Medan – Ten armed gunmen stormed the Hamparan Perak Police Precinct in Medan, North Sumatra, early on Wednesday morning, killing three police officers.

Hamparan Perak was one area raided by the elite Detachment 88 (Densus 88) antiterror police unit over the weekend.

North Sumatra Police spokesman Sr. Comr. Baharudin Djafar told the Jakarta Globe on Wednesday that 10 men riding six motorbikes arrived at the police station in Deli Serdang around 1 a.m. "The men immediately opened fire and killed an officer at the front desk and two more inside," Baharudin said.

The victims were identified as Chief Brig. Riswandi, Adjutant First Insp. Sinulingga and Adjutant First Insp. Deto Sutejo.

North Sumatra Police Chief Insp. Gen. Oegroseno said that one of the victims, Riswandi, was shot six times, including once to the head. "Another was shot 9 times and the other 4 times," he said.

The assailants also threw two Molotov cocktail bombs at a patrol car. "We can tell that the attack was well planned and the perpetrators were trained with guns," Oegroseno said. "The Mobile Brigade [Brimob] is after them," he said, referring to the armed police unit.

Oegroseno said he had immediately reported the attack to the National Police Chief Gen. Bambang Hendarso Danuri.
