An associate of Ukraine`s deposed president says the former leader`s son has died in an accident in which a vehicle plunged through the ice of Lake Baikal in Russia.

Nestor Shufrych, a deputy in Ukraine`s Parliament, said Sunday in a statement on Facebook that the 33-year-old Viktor Yanukovych, who had the same name as his father, was driving at the time of his death. He gave no further details.

Russian authorities haven`t identified the driver who died Friday when a minibus carrying six people crashed through thin ice on the Siberian lake or confirmed reports that it was Yanukovych`s son. Five passengers survived.

The former president has lived in Russia since being toppled from power last year. He also has an older son, 41-year-old Alexander, a wealthy businessman.
