Opposition activist Sergei Mokhnatkin, who was arrested on suspicion of committing violence against police at a protest demonstration on Triumphalnaya Square in Moscow on December 31, 2013, has declared a hunger strike, Sergei Tsygankov, a spokesman for the Russian Federal Corrections Service department for Moscow, told Interfax on Saturday.

"It is true that Mokhnatkin has submitted a written statement to the head of the SIZO-2 [detention center] administration and has been on a hunger strike since yesterday," Tsygankov said.

In line with the detention center's regulations, Mokhnatkin has been placed under permanent medical control, and all food products except water have been withdrawn from him, he said.

Mokhnatkin is currently being held at a solitary confinement unit for breaking the rules of stay under arrest, as he refused to be fingerprinted upon having been delivered to the detention center, Tsygankov said.
