"He died because of a congenital disease," Veera Somkwamkid, one of the PAD leaders, said.
Somrit suffered heart failure while he was walking to the medical tent at Phitsanulok Road in front of Government House.
The medical team provided him emergency aid by pumping his heart but his condition did not improve. He was sent to Vachira Hospital in an ambulance but he could not be rescued.
The PAD medical team said Somrit suffered from a heart disease. The hot temperature during the demonstration aggravated his condition.
Veera has asked PAD protesters to mourn the death of Somrit.
