The secretary of Bogor regency's Culture and Tourism Agency, Zuryawan Irvandiar Zoebir, died after an altercation with another road user identified as Olive Leonardi, Bogor City Police reported on Sunday.
Bogor City Police chief detective Adj. Comr. Hendrawan Nugraha was quoted by kompas.com as saying the police had questioned several witnesses.
"We have investigated the crime scene and taken the body for a forensics examination," Hendrawan said on Sunday.
The detective said the incident began with Zuryawan and Leonardi battling to enter the Bogor Outer Ring Road, heading from Sentul to Bogor, on Saturday.
"The tension continued when they entered the toll road and they continued to take each other over. It seems that the victim said something that made [Leonardi] angry," Hendrawan said.
Witnesses reported that the two stopped their cars and fought. During the fight, Zuryawan fell and lost consciousness. Other road users stopped to help, but he died on the way to the hospital.
The preliminary forensics report found an open wound on Zuryawan's forehead and a bruise on the left side of his chest.
