Turkish police on Wednesday arrested one of President Recep Tayyip Erdoğan's key rivals and Istanbul's mayor, Ekrem İmamoğlu, amid a larger crackdown on the opposition.
A statement from the Istanbul Public Prosecutor's Office called İmamoğlu a "criminal enterprise ringleader." He was detained among 100 others, including his close aide Murat Ongun and election campaign manager Necati Özkan.
