Russian police arrested opposition activists on Friday and warned against any illegal assembly this weekend.
The move comes after a dissatisfied opposition coalition urged voters to protest in the capital.
Many politicians, mostly communists, have stood together saying the online system of voting is corrupt.
They said the system cheated them of victory in the parliamentary voting and called for the system’s removal.
The Communist Party has called voters to meet lawmakers on Saturday and demanded Moscow revise the vote result.
The party is viewed as a ‘systematic’ opposition, which the Kremlin tolerates and provides it with parliament seats.
The OVD-Info protest monitor said the police arrested and attempted to arrest nearly six people on Friday over Monday’s protests.
The final election results released on Friday had handed 324 of Duma’s 450 seats to the Putin-backing United Russia Party.
Moscow and several other regions used the electronic voting program in last week’s election.
Moreover, the Kremlin showed a desire to roll out electronic voting across the nation in future voting.
Moscow mayor’s office said they did not authorize the Communist Party rally due to the COVID19 pandemic.
Additionally, the Police said the unauthorized street rallies put the public order and health at risk and they must stop it.
However, the head of the Communist Party, Gennady Zyuganov, said to RIA news that the rally was completely legal.
Officers brought in 30 people this week due to a similar protest on Monday after the election, the Police stated.
They added that the Police are still searching for other protesters.
Marina Litvinovich, a participant of the opposition coalition, said they would hold similar gatherings in the future, Reuters reported.
She added that the protest gatherings will depend on the number of people who show up in Moscow on Saturday.
