The bomber, identified as Salih Necar, was thought to have entered Turkey with refugees from Syria. His fingerprints were taken when he entered the country, which was how police identified him.
Saleh Nejar, member of PYD / YPG, Syrian wing of the PKK terrorist organization, was born in 1991.
His dismembered body was found at the scene. Two persons being reportedly in contact with Salih, who entered Turkey in July last year, were detained.
