Melek Çetinkaya, the mother of an imprisoned military cadet, Salih Gergerlioğlu, the son of an imprisoned law maker, and İbrahim Demiryürek, a human rights activist, were briefly detained by the Turkish police for staging a protest to demanding the release of Ömer Faruk Gergerlioğlu from prison in line with a top court ruling on Monday evening.

The trio was released several hours after detention. They are known with their public protests against a series of purges by the government of Turkey enabled by a state of emergency in reaction to the 15 July failed coup d’état.

Ömer Faruk Gergerlioğlu, a former MP from the pro-Kurdish Peoples’ Democratic Party (HDP) and a prominent human rights activist, was stripped of his status in parliament on March 17 after conviction of disseminating “terrorist propaganda” in a 2016 social media post, was taken into custody on April 2 and sent to prison.

The Constitutional Court on July 1 ruled for Gergerlioğlu’s release on the grounds that his rights were violated. Despite the ruling, however, he is still being held in Ankara’s Sincan prison.
