In the latest iteration of Russia’s ongoing crackdown on dissent, a Moscow court on Friday ordered the detention of Grigory Melkonyants, co-chair of independent election monitoring organization Golos.

The organization announced in a statement that the initial detention period was set at two months pending an investigation into charges that Melkonyants organized the activities of an “undesirable” NGO– a crime in Russia, punishable with six years in prison.

Melkonyants’ arrest came amid a flurry of searches of the homes and offices of Golos associates in recent days, according to the statement. The organization attributed the timing of the arrest and searches to Russia’s upcoming elections:

“We are convinced that the true purpose of this attack on Golos is to prevent public observation on the eve of the Russian presidential election campaign and the upcoming September 10 regional elections. Some high-ranking officials are not concealing this fact.”

Russia’s pursuit of opposition-minded activists has been relentless since the country’s invasion of Ukraine. Earlier this year, Amnesty International’s Russia director, Natalia Zviagina, described the situation:

“In the past two years, the Russian government has only intensified its witch-hunt of opposition and civil society organizations. Not one critic, human rights defender or independent journalist is safe from the threat of persecution, reprisals and repression.”
