MOSCOW, December 1 (RAPSI) - Russian activist Ildar Dadin sentenced to 2.5 years in prison for numerous violations of protest laws has been put in solitary confinement for 6 months, his wife Anastasia Zotova wrote on her Facebook account on Thursday.

Reportedly, he was punished for a fight with his cellmate.

Dadin was convicted on December 7, 2015. Initially he received a 3-year prison term. The Moscow City Court later reduced the sentence to 2.5 years.

Zotova wrote on Facebook in early November that her husband had been beaten and received murder threats when transferred to a penal colony in Karelia. The Federal Penitentiary Service (FSIN) launched a probe into the allegations. Later, the FSIN announced that independent medical commission from a local hospital had not found injuries on Dadin’s body.

On November 24, members of the European Parliament (MEPs) during a plenary session expressed concern over the welfare of Dadin and called on Russia to immediately release him. MEPs insisted on a thorough and transparent independent investigation into the situation with Dadin who had complained on a number of occasions of prison conditions and torture.
