On 11 July 2005, the office of the Donetsk Oblast Prosecutor charged Yanukovych with fraud, stemming from alleged irregularities in the way his convictions were expunged twenty years earlier. In 2006, the General Prosecutor closed the case due to lack of evidence. In 2006, a criminal charge was filed for official falsifying of documents concerning the quashing of Yanukovych's prior convictions after it was discovered that two documents had been tampered with, including the forgery of a judge's signature in connection with one charge of battery.
