On May 18-21, 2006, in St. Petersburg, law enforcement authorities rounded up and arrested a group of skinheads suspected of a series of racist killings committed in the city in 2004 and 2005.

On 18 May, police attempted to arrest Dmitry Borovikov, leader of Mad Crowd gang, a wanted suspect since 2004. (To remind, 6 members of the group were convicted in December 2005). Dmitry Borovikov was suspected, in particular, of killing Samba Lampsara, a student from Senegal, on April 7, 2006. When police attempted to arrest him, Dmitry Borovikov, armed with a knife, resisted the police and was wounded in the fight by a policeman. The wound was fatal, and Dmitry Borovikov died in hospital.

Five more people suspected of racist assaults were arrested in St. Petersburg in the following few days. The homes of all arrested suspects were searched; police found explosives, as well as extremist literature. We can conclude from the police reports of the incident that all detainees were members either of Mad Crowd or an associated group. In addition to the murder of a student from Senegal, the arrested individuals are suspected of a racist attack against an Armenian in 2003, of killing a Vietnamese national in the same year, and of killing Nicolay Girenko, researcher and anti-fascist, who testified as expert at the trial of another skinhead gang, Schultz-88 (its organizer and member were convicted after the researcher's death, in December 2005).

Besides, the arrested suspects are believed to have killed two members of their own gang, of preparing a blast attack against a cafй in St. Petersburg frequented by African students, and a series of armed robberies of post offices and Sberbank.
