A total of 1,029 people were taken to police stations, says

One of the eyewitnesses, Ilya Azar, shared his impressions of the rally in Moscow: "The police were harsh, actively employing truncheons despite their "tourist police" patches. There were many detentions (please, visit the [World] Cup). Protesters were beaten not only by police, but also by various 'comrades' sporting St. George ribbons, as well as 'Cossacks' (including, with whips). In general, the rally saw more 'civil defense' forces and other regime supporters than ever before," he wrote in a social network.

Also, according to media reports, parents are not allowed to underage detainees in Moscow.
