The governorate confirmed in a written statement that a bomb setup was used in the explosion that occurred at a tax office in capital's Çukurambar neighborhood.
The statement added that security footage of the scene showed a male suspect with a bag placing and preparing the bomb setup at the entrance of the building.
Police units launched an operation targeting the primary suspect and eight other affiliated suspects. Two of the four suspects who escaped in the same car as the main suspect were detained in southern Osmaniye province, while the remaining two were caught in southern Adana province.
The four remaining suspects were detained in Şırnak and Mardin provinces, after police units identified them to be in contact with the bombing suspects.
The statement said that the main suspect identified as Ersen Ertogan was caught dead. The 26-year-old, who received training in a YPG-held area in Syria, was carrying a fake ID card and reportedly entered Turkey illegally.
