An abandoned car near the crime scene was investigated and tracked by police. As a result, on 28 October, 5 people from Istanbul, Şanlıurfa, Adıyaman and Diyarbakır were arrested related to the attack,[15][16] which the Turkish authorities blamed on the PKK.[3] The PKK claimed responsibility for the attack 3 days after the bombing, and said that Turkish media reports of the incident included “disinformation“ but did not elaborate further.[17]
