Turkey detains 37 over ’provocative’ social media posts following arrest of Istanbul mayor Ekrem Imamoglu

Turkish authorities detain 37 for social media posts, including Istanbul mayor, sparking protests and financial market concerns.

“Turkish authorities detained 37 people for sharing “provocative” content on social media,” the Interior Minister said on Thursday (March 20, 2025), pressing ahead with a crackdown on dissenting voices that escalated with the arrest of the mayor of Istanbul, a potential challenger to President Recep Tayyip Erdogan.

Mayor Ekrem Imamoglu was arrested after a dawn raid on his residence on Wednesday (March 19, 2025) as part of investigations into alleged corruption and terror links. Several other prominent figures, including two district mayors, were also detained.

The detention of a popular Opposition leader and key Erdogan rival deepened concerns over democracy and sparked protests in Istanbul and elsewhere, despite a four-day ban on demonstrations in the city and road closures. Several people were detained following a student protest in the capital Ankara that continued into the night. It also caused a shockwave in the financial market, triggering temporary halts in trading to prevent panic selling.

Critics see the crackdown as an effort by Mr. Erdogan to extend his more then two-decade rule following significant losses by the ruling party in local elections last year. Government officials reject claims that legal actions against Opposition figures are politically motivated and insist that the courts operate independently.

Interior Minister Ali Yerlikaya said authorities identified 261 social media accounts that shared provocative posts inciting public hatred or crime, including 62 that are run by people based abroad. “At least 37 of the suspected owners were detained in a operation police and cyber crime teams,” he wrote on the X social media platform. “Efforts to detain other suspects were continuing,” he said.

Mr. Imamoglu's arrest came just days before he was expected to be nominated as the Opposition Republican People’s Party's Presidential candidate in a primary scheduled for Sunday (March 23, 2025). The party’s leader has said the primary will go ahead as planned.

Prosecutors accused Mr. Imamoglu of exploiting his position for financial gain, including the improper allocation of government contracts.
