MOSCOW, August 28 (RAPSI) – Ukraine’s Prosecutor General’s Office has revoked its decision to extradite Adam Osmayev, who is suspected of plotting Vladimir Putin’s assassination, RIA Novosti reported on Wednesday citing Osmayev's attorney Olga Chertok.

In February 2012, Russian and Ukrainian security services reported that the suspects in the case, who were earlier placed on the international wanted list, had been arrested in the city of Odessa. 

The gang, including Chechen-born Adam Osmayev and Ruslan Madayev with Kazakh-born Ilya Pyanzin, was exposed in January 2012 after a bomb accidentally detonated in their apartment, killing Madayev.

Pyanzin told Ukrainian security officers that his accomplices were preparing a bomb to assassinate then Prime Minister Vladimir Putin and Chechen leader Ramzan Kadyrov. They allegedly planned to detonate it close to Putin's motorcade as he drove through Moscow.

Pyanzin was extradited to Russia in 2012.

In September 2013, the Moscow City Court found Pyanzin guilty of plotting to assassinate Putin and sentenced him to 10 years in prison.

Ukraine has backtracked on an earlier decision to extradite Osmayev because of his complaint which had been filed with the European Court of Human Rights (ECHR), Chertok said.

Osmayev claims that his extradition would result in violation of his rights.

When asked by the ECHR, Ukraine failed to stand its ground and justify its decision to hand over Osmayev to Russia, Chertok said.
