A North Caucasus man held in custody on suspicion of involvement in the assassination of Russian opposition politician Boris Nemtsov has retracted his confession, according to a local media report.
The development would mean that now none of the five suspects held over the murder admit their guilt, the report said.
An "informed source" told the Rosbalt news site that suspect Shadid Gubashev retracted his confession on September 24, claiming he was tricked and pressured by investigators.
Two other suspects, Zaur Dadayev and Anzor Gubashev, initially confessed to the crime before withdrawing their statements to investigators, saying they had been coerced and tortured.
Nemtsov was shot dead near the Kremlin late on February 27 as he strolled home with his girlfriend.
