The case officer, LtColonel Yannawut Liamkaew, said the negotiations had "nothing to do" with the criminal charges of murder, attempted murder and assault against Kanpitak, which the police investigator will conclude for the Criminal Court within a week.
Further talks will be on September 14.
Prior to the negotiations at Thong Lor police station, Kanpitak's mother, a former Miss Thailand, Savinee Pakaranang, told reporters that she would talk about compensation with four more victims out the 12 affected people eight of whom had already agreed to the compensation proposed.
However, Savinee later told reporters the twohour talks did not reach any conclusion and her side wanted each victim to submit details of the damages claim to help her understand why they wanted such a large amount of money.
One injured victim, Sangwan Srihawong, 40, initially asked for Bt6 million, but following discussions with Sangwan's lawyer Prakobrat Dechakul - the amount was lowered to Bt3 million, Savinee said.
Sucheera Insuwan, 25, whose mother Saichol Luangsaeng, 42, was killed in the incident said the Bangkok Mass Transit Authority (BMTA) sent a lawyer to help her family seek compensation and that she initially asked for Bt7 million, which she was in process of negotiating.
"Such an amount of money can never replace my mom's life," she said, adding that the BMTA had also assisted the family by hiring her for her mother's position as a BMTA account.
Two other victims, bus driver Sathaporn Arunsiri, 37, and bus conductor Somjit Klaewkla, 35, who were both slightly injured asked for Bt70,000 and Bt73,000 in compensation respectively.
LtColonel Yannawut Liamkaew said if both parties could agree upon compensation, they would no longer need to file a civil lawsuit, he added.
In the July 4 incident, a Mercedes Benz slammed into a crowd of people who had just been ordered to alight from a bus. This followed an accident between the bus and the car and an altercation between the two drivers.
The Pachimsawas family claimed Kanpitak, who was identified by witnesses as the Benz driver, suffered from epilepsy and that he had been treated at a mental hospital this year.
