An Iranian man who set himself on fire after municipal workers shut down his family’s food stand has died from his injuries, prompting the country’s president to order an investigation.

Axar.az reports, AP, the announcement Tuesday night by President Masoud Pezeshkian came as a district mayor and the head of the enforcement arm in the southwestern city of Ahvaz were arrested over the incident, the state-run IRNA news agency reported. Warrants have been issued for three others in connection with the case, IRNA said, as the man’s death sparked a renewed public debate over poverty in the Islamic Republic.

Ahmad Baledi, 20, died Tuesday after the fire burned 70 percent of his body. He set himself ablaze Nov. 2 in a park in Ahvaz in Iran’s oil-rich but long-restive Khuzestan province, as municipal workers closed down the stand, his family’s only source of income.

Initially, Ahvaz’s municipality issued statements describing the closure as a court-sanctioned eviction and said officials took “no coercive action.” But Pezeshkian’s order on Tuesday called on interior ministry to launch a special investigation and condole the Baledi family.
