The members of the group face new charges of staging a public event without having prior permission, an offence that carries a jail sentence of up to 10 days or a fine of up to 30,000 rubles (£365.8), Russian news agencies reported.
Nikolai Vasilyev, the group's lawyer, said police had not yet allowed him to see the case materials, and he was unable to confirm what charges his clients faced, or when a court hearing would be held.
The activists briefly interrupted the football World Cup final on July 15 when they ran onto the pitch in police uniforms.
Their intrusion onto the pitch in Moscow's main stadium in front of President Vladimir Putin and other high-ranking officials marked a rare security breach in the weeks-long football tournament hosted by Russia.
The group said the stunt, which held up the game only briefly, was meant to promote freedom of speech and condemn policies of FIFA, football's global governing body.
The four pitch invaders were jailed for 15 days for the stunt and were banned from sporting events for three years.
The four members were Veronika Nikulshina, Olga Pakhtusova, Olga Kurachyova and Pyotr Verzilov.
Tournament organisers said the stewards who failed to stop the intrusion would face disciplinary action.
