A deputy chief of police in Istanbul was arrested early Aug. 18 over the killing of a motorcycle rider following a road-rage incident.Celal Yılmaz, 51, entered a quarrel with motorcycle rider Ahmet Sülüsoğlu, 32, while he was heading home with his wife in the Halkalı district after Sülüsoğlu rode toward his car. The quarrel subsequently ended, and Yılmaz proceeded toward home.However, Sülüsoğlu reportedly pursued Yılmaz, resulting in a second quarrel between the two at around 1 a.m. in front of the couple’s lodging building. As the quarrel resumed, Sülüsoğlu pointed a gun at Yılmaz but was immediately shot dead before firing. A subsequent investigation revealed the gun to have blank cartridges.Yılmaz informed police and medical teams about the incident. He testified in a police station before being transferred to a court, where he was arrested.Yılmaz was promoted to the rank of first-degree police chief two months ago and is responsible for the Büyükçekmece, Çatalca, Beylikdüzü and Silivri districts of Istanbul.Below is security footage from the moment when Yılmaz shot Sülüsoğlu.
