This is contained in a statement issued by the spokesman of the Economic and Financial Crimes Commission, EFCC, Wilson Uwujaren, in Abuja on Thursday.
He stated that the convict was arraigned before Justice Abubakar Umar on November 7, 2012.
Gilmaska was found guilty of forging and issuing a cheque of N9 million to one Tayo Olugbemi, sometime in 2012.
She pleaded not guilty to the charge.
Uwujaren said the Polish woman would be sentenced alongside her company, Icon Media and Marketing Agency Limited.
“The sentence was reserved after the convict was found guilty of a one-count charge of fraud brought against her by the EFCC,” he added.
