Ukraine's Prosecutor-General's office says it has revived an investigation into the alleged embezzlement of about $3 million and evasion of some $2.5 million in taxes by jailed former Prime Minister Yulia Tymoshenko when she headed an energy firm 15 years ago.
Ukraine's main opposition leader was sentenced to seven years in prison earlier this month on charges of abuse of office.
Her lawyers say she has decided to appeal and papers would be filed on October 25.
The United States and the European Union have condemned the case as politically motivated.
Tymoshenko says she is the victim of a political vendetta by President Viktor Yanukovych.
A new charge brought against her since she was jailed alleges that she took part in a "criminal conspiracy" in the 1990s to embezzle state funds, resulting in $405 million of debt to Russia.
