A feud between pro-Kremlin Nashi activists and Oleg Mitvol, prefect of Moscow's Northern Administrative District, escalated on Wednesday when they hung a giant poster of Mitvol on a building in his district that they said housed a brothel.
The activists said they have identified more than 30 brothels in the district and that Mitvol ignored their findings, which forced them to act.
Mitvol said an investigation has been opened into the activists because they broke into the building's loft to hang the poster. He also denied receiving information about brothels from Nashi.
Mitvol and Nashi clashed last week after the prefect demanded that the group vacate its headquarters, located in his district, because the building was to be turned into a kindergarten.
