Russian football fans came together in a rare show of unity this weekend to protest police violence as scores of hardcore supporters staged walkouts across matches in the top division.
The leading supporters' group at Spartak Moscow called for the boycott on Friday, urging fans to leave the ground in the 30th minute.
The protest was launched in response to incidents ahead of last week's fixture between Zenit and Spartak, when 150 to 200 fans were arrested in Saint Petersburg.
The "Fratria" group, the association behind the boycott, in a statement denounced them as "arbitrary arrests, without explanations".
While the supporters of the two clubs are known for their animosity and the match was considered one at risk, no acts of violence had been reported at the time.
A witness, cited by the R-Sport news agency, recounted "police raids in bars and in the city streets. The people living in Moscow were arrested and taken to police stations where they were accused of hooliganism."
"What happened in Saint Petersburg is simply the breaking point," a member of the "Fratria" group told AFP. "Before that loads of supporters of different teams had already been subjected to incomprehensible acts from police representatives."
