MOSCOW, May 27 (RAPSI) – Pretrial investigation into real estate tycoon Sergei Polonsky, who stands charged with large scale fraud, has been extended until July 11, the businessman’s lawyer Slavik Brsoyan told RAPSI on Wednesday.

Polonsky, deported from Cambodia on May 17, has been taken to a detention facility in Moscow. He refused to testify.

Interior ministry spokeswoman, Yelena Alekseyeva, told journalists earlier that Polonsky will undergo a mental exam.

Polonsky was charged in Russia in absentia in July 2012 as part of a criminal case involving the embezzlement of over $175 million from the investors in an up-market condominium project in central Moscow.

In November 2013, Polonsky was arrested in Cambodia at Russia’s request, only to be released in January 2014.

On January 13, 2014, Moscow's Tverskoy District Court seized the stock of foreign companies owned by Polonsky, who assessed them at $100 million.

In 2008, Forbes ranked Polonsky Russia's 40th richest man with a $4.35 billion fortune. His Mirax Group, a property development company, went bankrupt during the global economic recession.
