If convicted, Tsikhanouski and the other detainees face up to three years in prison. One of the individuals is also charged with assaulting two law enforcement officers and may face up to 6 years in prison if convicted.

Tsikhanouski was supposed to be released from jail on June 8 after finishing his 10-day incarceration for taking part in the unsanctioned rally on May 29.

He was not released and city authorities have said they will explain later why he remained in custody.

Tsikhanouski is the owner of a popular YouTube channel called "The Country for Life," which challenges Belarusian authorities.

Before his 10-day incarceration, Tsikhanouski was jailed in May for several days for organizing and taking part in other rallies.

On May 15, the Central Election Commission rejected Tsikhanouski's registration documents for his candidacy for the presidential election scheduled for August 9.

Since Tsikhanouski's candidacy was rejected, his wife Svyatlana Tsikhanouskaya has been trying to get registered as a candidate herself, collecting the necessary 100,000 signatures to qualify.
