BANGKOK - Initial investigation into a case in which a Bangkok businessman rammed his BMW into an alleged robber's motorbike, killing him instantly, on Thursday night showed that the deceased suspect had committed similar muggings several times before. Thawich Kitniyom, 32, claimed that he was robbed at knifepoint by the motorcyclist - later identified as Somkuan Thaidecha - while he was waiting to make a U-turn in front of Lat Phrao Soi 130.
According to the investigation so far, Somkuan, who was on a motorcycle, stopped and knocked on Thawich's car window.
Thawich rolled down the window, thinking Somkuan wanted directions, but was punched in the face and held at knifepoint until he gave up his valuables. Somkuan then fled and Thawich began to give chase, Thanee said.
After being mugged, Thawich said he decided to give chase, claiming that he was tailing the suspect until they reached the three-way junction at Soi Nawamin 14, when the suspect took a sudden turn and Thawich's speeding car rammed into him.
The impact sent the car along with the suspect on his motorbike into a roadside shophouse, and Somkuan died instantly.
Lat Phrao superintendent Pol Colonel Withawat Chinkham said initial investigation showed that the suspect had robbed others in the same manner, except this time the alleged victim decided to give chase.
Police said they had to investigate the case further to determine whether Thawich intended to kill the man before taking legal action. Withawat said all sides would be treated justly.
Lat Phrao investigator Pol Major Thanee Jitham said Somkuan was a former convict and had committed previous robberies, while Thawich worked as clothing designer.
