Istanbul police on Saturday arrested a woman suspected of involvement in a 2015 attack that targeted the US consulate in the city, the local governor's office said.
The suspect, identified as Hatice Kılıç and said to be a member of a banned far-left group, was arrested in the Avcilar district of Istanbul, it added.
Following intelligence reports suggesting Kılıç and Serkan Örs were residing in Istanbul, the security forces launched the operation and arrested them.
In addition, Turkish security elements found a gun, bullets, and digital and organizational documents affiliated with the terror group.
Two armed women launched the attack in August 2015 against the fortified US consulate located in the quiet district of Istinye on the outskirts of Istanbul.
One was wounded, and apprehended soon after the attack, but Kılıç escaped and authorities offered a reward of 1.5 million lira (250,000 euros) for information leading to her capture.
The Revolutionary People's Liberation Army-Front (DHKP-C) claimed the attack. The group had already targeted the US embassy in Ankara in 2013, killing a Turkish security guard.
The group is listed as a terrorist organization by Turkey, the U.S., and the European Union.
