Alexander was arrested in May 2021 and convicted in September of that year of "violence or threat of violence against law enforcement officers." According to investigators, on October 12, 2020, on Dzerzhinsky Avenue in Minsk, he and others, while intoxicated, resisted police officers, threatened them with violence, and threw a beer glass toward a police bus. He pleaded not guilty to the crime.
In October 2022, a court hearing was held on the charge of "malicious disobedience to the demands of the administration of a correctional facility," as a result of which Alexander was sentenced to another year of imprisonment.
He was released in December 2023, having fully served his sentence.
