Adana police briefly detained visually impaired journalist Cüneyt Arat  for “insulting President Recep Tayyip Erdoğan” in a tweet he posted.

Arat was detained by four police officers early on Wednesday and questioned on suspicion of “insulting” President Erdoğan. He was released immediately after questioning at the Anti-Smuggling and Organized Crime Bureau of Adana Police Department.

“They sent four police officers to detain me. Have you not told them I was visually impaired?” Arat asked Erdoğan in a tweet after his detention.

“They told me I was suspected of insulting Erdoğan until they took me to the police station. Once I was there, they told me my crime was making propaganda of the [so-called] FETÖ [Fethullahist Terrorist Organization,” Arat said in another tweet.

Arat was sentenced on Feb. 22 to 6 years 3 months in prison due to his alleged links to the Gülen movement, which the Turkish government accuses of masterminding a coup attempt on July 15, 2016.

Arat tweeted that he was also given one year, 10 months and 15 days jail time for promoting a “terrorist” organization.

“I was given 6 years, 3 months over movement membership. I was also given 1 year, 10months and 15 days for [Gülen] propaganda. I am acquitted of coup involvement accusations.” Arat said in his tweets.

Arat was arrested on July 21, 2016, for social media posts that allegedly praise the Gülen movement. The disabled journalist has been under house arrest wearing an electronic ankle bracelet since then.
