MOSCOW, June 17 (RAPSI) - Temerlan Eskerkhanov who stands charged with murder of Russian opposition politician Boris Nemtsov has applied to the European Court of Human Rights (ECHR), RIA Novosti reported on Friday.

Eskerkhanov claims in the complaint that Russian authorities violated his rights to effective investigation and effective remedy.

He also insisted that he had been beaten during his arrest. 

Earlier, the suspected killer of Nemtsov Zaur Dadayev turned to the ECHR over alleged torture.

Nemtsov was murdered in central Moscow on the night of February 28. In the 1990s, the politician held a number of high-ranking posts in the Russian Government. In the 2000s, he joined the opposition.

Pretrial investigation into the case has been completed. Zaur Dadayev, brothers Anzor and Shadid Gubashev, Temerlan Eskerkhanov and Khamzat Bakhayev have been charged with contract murder and illegal acquisition, carrying and keeping of weapons.

Alleged organizers of the murder still remain under investigation. Ruslan Mukhudinov, a former officer in Chechen Interior Ministry and alleged mastermind of the murder have been placed on the international wanted list.
