MOSCOW, May 20 (RAPSI) - Real estate tycoon Sergei Polonsky, who stands charged with large scale fraud, will undergo a mental exam, Interior ministry spokeswoman, Yelena Alekseyeva, told journalists on Wednesday.

Polonsky was deported from Cambodia to Russia on Sunday. 

The reason for his departure was overstaying his visa.

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.
