(CNN) Pussy Riot claimed responsibility for a group of protesters who took the field during the final World Cup match in Moscow on Sunday, indicating in a statement that the field invasion was staged to bring attention to political injustices in Russia.

Minutes into the game's second half, four protesters dressed as policemen ran onto the field at Moscow's Luzhniki Stadium, interrupting play.

Security personnel jumped into action and began removing the protesters -- but not before one of them managed to get a double-handed high-five from France's 19-year-old star Kylian Mbappe.

In a statement posted to Twitter and Facebook, the Russian punk band and activist group called for political prisoners to be freed, for the arrests of opposition protesters to cease, and for the jailing of citizens for their social media activity to end.
