A group of young people on Wednesday night broke into the Uman synagogue on the grave of Rabbi Nachman, sprayed the walls and floor with red paint and hurled chunks of pork around.
The perpetrators reportedly left behind a pig's head with a swastika carved on it.
A few worshipers who were in the building at the time managed to escape and called the police, who arrived at the scene when the hooligans have already escaped. Media believe that the pogrom was staged by a group Ukrainian nationalists.
Police has said they opened criminal proceedings on the charges of hooliganism at the Tzaddik Nachman gravesite complex. The case was soon requalified under Par. 3, Art. 161 of the Criminal Code of Ukraine (violation of the equality of citizens regardless of their race, ethnicity or attitude to religion), which provides for a penalty of imprisonment up to eight years.
A number of physical evidence was found on the scene," a police report reads.
