PATHUM THANI — Police said Wednesday they had yet to charge or even question the son of a famous actor involved in a fatal high-speed auto accident earlier this week.

Kittiphum Iamsook, 28, slammed his BMW into another car at a U-turn in Pathum Thani on Monday, killing a 47-year-old engineer inside. Kittiphum was still in the hospital Wednesday for what are said to be minor injuries to his arms and chest, while his father publicly apologized on his behalf.

“We have not charged him yet because we need to collect evidence first,” Col. Teerawat Khachornphas, chief of Thanyaburi Police Station, said by telephone. “He will be questioned soon, after he leaves the hospital.”

Teerawat also said Kittiphum was given a sobriety test, but the results have not yet been made public.

Kittiphum’s father is Choosak Iamsook, a celebrity comedian with many film credits known by his stage name Nhong Cha Cha Cha.

On Tuesday night Choosak attended the funeral for Ponpichit Naruematmontri and apologized to his family on Kittiphum’s behalf. Choosak said his son could not come to the funeral because of his injuries.

Choosak also offered an unspecified amount of financial compensation to Ponpichit’s family.

On Wednesday the victim’s widow said she wants Choosak can help her son find a job because the family has lost its main breadwinner.

“After the funeral is over we will talk about assistance, about what he can help us with,” Kasemsi Kaewkla said.
