ISTANBUL. March 21. (AP): Protests erupted across multiple Turkish cities on Friday as people rallied against the arrest of Istanbul’s mayor and top rival to President Recep Tayyip Erdogan, despite the Turkish leader's stern warning that street protests would not be tolerated. In Istanbul, police used pepper spray, tear gas and rubber bullets to push back hundreds of protesters who tried to break through a barricade in front of the city's historic aqueduct and threw flares, stones and other objects at them.

Police also broke up demonstrations in Ankara, the capital, as well as in the Aegean coastal city of Izmir, resorting to forceful measures at times, according to images shown on the private Halk TV. Thousands marched in several other cities calling on the government to resign, the station reported. At least 97 people were detained nationwide during the protests, Interior Minister Ali Yerlikaya said. Mayor Ekrem Imamoglu was arrested in a dawn raid on his residence on Wednesday over alleged corruption and terror links, escalating a crackdown on opposition figures and dissenting voices.

Several other prominent figures, including two district mayors, were also detained. Many view the arrest as a politically driven attempt to remove a popular opposition figure and key challenger to Erdogan in the next presidential race, currently scheduled for 2028. Government officials reject accusations that legal actions against opposition figures are politically motivated and insist that Turkey’s courts operate independently.

Imamoglu was questioned by police for four hours over corruption accusations, during which he denied all the charges, the Cumhuriyet newspaper and other media reported. He was expected to be transferred to a courthouse Saturday evening for questioning by prosecutors. His arrest has sparked the largest protests since 2013, when Turkey was rocked by mass anti-government demonstrations that left eight people dead.

Earlier on Friday, the leader of Turkey’s main opposition party, Ozgur Ozel, renewed a call on supporters to take to the streets for peaceful demonstrations, while authorities widened a ban on protests and criticized the appeal as irresponsible. "I invite tens of thousands, hundreds of thousands, and millions, to peacefully demonstrate, express our democratic reaction, and exercise our constitutional rights,” he said.

Addressing a large rally outside the city hall, Ozel accused Erdogan of using the judiciary as tool after failing to defeat the mayor "in a fair way.” Erdogan, increasingly authoritarian after more than two decades in office, said the government would not tolerate street protests and accused the opposition party of links to corruption and terror organizations.
