Mahmut Karaaslan, the new police chief of Turkish capital Ankara who started his duty following the deadly car bombing on March 13 that killed 35 civilians, drove around the city unnoticed for three days with license plates belonging to stolen cars to test the city's surveillance cameras and license plate recognition system.

According to an article of Turkish daily Sözcü, Karaaslan drove in the city's main arteries and streets monitored by 1,400 surveillance cameras for three days in a row. 41 different license plates sought by the police were tried on the car driven by Karaaslan, all going unnoticed by the city license plate recognition system installed in 513 different places around the city. The police chief also went unnoticed in police checkpoints in different parts of the city.

Karaaslan warned related police commissioners regarding his inspection, and asked necessary measures to be taken. The article stated that the recognition system didn't detect license plates with seizure orders or duplicated plates as it slowed the whole system down.

With its increasing involvement in the civil war in Syria and the anti-Daesh campaign in Iraq, the PKK started adopting new tactics in its armed insurgency against the Turkish state, which includes car bombings and erecting explosive-laden barricades in urban areas. The car bombing attack carried out on February 17 that killed 29 people in Ankara was carried out by a stolen car by a terrorist from hardliner PKK group named TAK, who was trained by the PKK's Syrian offshoot YPG.

Another car bombing was carried out by PKK terrorists killed 35 civilians in Ankara on March 13.

The Turkish capital was also targeted by a twin suicide bombing carried out by the Daesh terror organization on Oct. 10, 2015, killing 103 people in a peace rally.
