Eren Erdem, a former main opposition deputy and a member of the Republican People’s Party (CHP), tweeted early on Friday that he was taken into custody by police in front of his house.

“I was just detained. I do not know the reason. I was detained by police in front of my house,” Erdem tweeted early on Friday morning.

Mr Erdem, an outspoken critic of the Turkish government and the management of his own party, CHP, was not included on his party’s nomination list for the June 24 general election.

Several week ago, a trave ban was imposed the former deputy by the Istanbul 35th High Criminal Court after the same court accepted an indictment that demands 22 years in prison for Erdem for his articles in the Karşı daily about the Dec. 17-25, 2013 corruption investigations, which implicated four ministers and President Recep Tayyip Erdoğan’s family. Erdem served as editor-in-chief of Karşı, which was established on Feb. 9, 2014 and closed due to financial problems after only 66 days of operation.
