Metropolitan Police Area 2 deputy chief Colonel Khomsak Sumangkaset yesterday said that case investigator Lieutenant Theerapol Hongsri had received the autopsy result on Friday that revealed Don Daengchantip had died from blood circulation failure combined with the fact that he had ischemic heart disease.
He said Don had resisted arrest, resulting in officers chasing and tackling him and causing his death.
The action would not have caused death under normal circumstances, he added.
Regardless, Khomsak said the seven officers had been charged with assault causing death, a crime punishable by between three and 15 years in prison.
The seven officers were shifted to administration work and their supervisor had filed this case with the Royal Thai Police to consider suspending them, he added.
