Jakarta. The driver involved in the fatal crash in West Jakarta's Jalan Daan Mogot which killed four people in early hours of Monday (08/02) has been charged with manslaughter and driving under the influence of alcohol, police said.

A car driven by the suspect Riki Agung Prasetio hit a motorcycle on Jalan Daan Mogot, West Jakarta, and then a tree at around 4:00 a.m. The two people on the motorcycle were killed as well as two passengers in the car. Three more car passengers were injured.

West Jakarta traffic unit deputy Comr. Hasbi Ibrahim told Tempo.co that Riki had confessed he was driving "at 90 to 100 kilometers per hour. And even though his urine test taken at the Cengkareng Public Hospital [West Jakarta] was negative for drugs, he said he had been drinking beers [before the incident].”

Riki and his eight friends had been at a karaoke booth cafe in Kalijodo, Angke, West Jakarta, before the incident and had consumed nine bottles of beer. Despite being under the influence of alcohol, Riki drove.
