One day after the assassination, the police announced that the shooter had been identified in video footage collected through both the Istanbul MOBESE electronic surveillance network (4,000+ cameras throughout the city) and local security cameras. They later released photos to the public while urging every citizen to aid with the investigation. On the same evening, Istanbul Governor Muammer Güler addressed the press to state that special investigation committees were pursuing nearly two dozen leads and that the police were analyzing ten thousand phone calls made from the vicinity of the crime scene.[citation needed]
