Makassar – A soldier was killed and three seriously wounded when a police truck rammed into a crowd of people amid a dispute between military troops and police officers in Manado, North Sulawesi.

Wirabuana military commander Maj. Gen. Arif Budi Sampurno, overseeing security in Sulawesi, ordered an investigation into the incident that took place early Sunday.

His spokesman Maj. Rustam Effendi said the dispute started after a group of policemen riding motorcycles hit Army soldier Second Sgt. Husni Daud.

The accident then drew a reaction from Husni's comrades. Fellow soldier Julius then asked local police about the matter but received an unsatisfactory response, according to Rustam.

One policeman opened fire, with a shot in the air, drawing attention from local residents, he added.

Minutes later, a police truck suddenly appeared and smashed into a crowd of people at the scene, killing Second Sgt. Ferly Ahmad and seriously injuring three other Army soldiers.

The three are currently in the intensive care unit at an Army hospital in Manado.
