Sergei Furgal, governor of the far eastern city of Khabarovsk, was interrogated and ordered to be held in jail for two months. Thousands of demonstrators have been gathering in the streets for three weekends to show their anger over the Kremlin's replacement of this popular regional governor. The sustained demonstrations represent a growing challenge for Putin, who is viewed as having a role in sparking the regional crisis after he fired Furgal. Many have called for his resignation. Others chanted ‘Disgrace’ and denounced the acting governor appointed by Putin. According to protest leaders and independent journalists, over 50,000 people demonstrated in Khabarovsk, which would make it the largest anti-government protest there since the collapse of the Soviet Union in 1991. Protesters see criminal charges raised against Furgal before his dismissal as unsubstantiated. They are demanding he stand trial at home instead of in Moscow, where he has been transferred.
