MOSCOW, May 13 (RAPSI) – Viktor Kudryavtsev, a 74-year-old scientist of the Central Research Institute for Engineering Technology (TsNIImash) charged with treason, has been transferred from a detention center to a municipal hospital for health examination following a decision of the European Court of Human Rights (ECHR), his attorney Ivan Pavlov has told RAPSI.

According to Pavlov, ECHR has obliged Russian authorities to conduct a medical examination of Kudryavtsev in a clinic independent of the penitentiary system. However, the lawyer claims, that the hospital where the researcher was placed in, does not fully meet the criteria specified in the ECHR ruling.

In March, the Lefortovsky District Court of Moscow extended detention of Kudryavtsev until May 20.

Earlier, Pavlov told RAPSI that investigators banned visits to the researcher after Kudryavtsev refused to make a deal with them envisaging guilty plea and testifying against his student.

Kudryavtsev is accused of disclosure of classified information to the Belgian Von Karman Institute for Fluid Dynamic, his another attorney Yevgeny Smirnov told RAPSI previously. Investigators claim that the researcher has transferred information via email from an unmarked computer. However, the scientist has not worked with such secret documents since late 90s, according to the lawyer.

The researcher pleaded not guilty and refused to testify in the case, Smirnov added.
