Once the investigation file was opened, it became clear that the officer, referred to by his initials "A.D." released detainees and even deleted the names of persons wanted for interrogation because of their alleged cooperation with Israel.It was further reported that the officer was first interrogated and then released in order to follow his movements and gather additional evidence.During the course of the investigation, a woman and four men, all of whom had ties with A.D., were also arrested.
