Chief Minister Parkash Singh Badal also asked the bureau to submit its report within a period of four weeks, an official spokesperson said.
The announcement came a day after the government had said it would set-up a high-level probe into the matter.
"The investigation will be personally supervised by Chief Vigilance Director Suresh Arora and he have been asked to submit the complete investigation report within four weeks," the spokesman said.
Ranike's PA Sarbhdyal Singh has been accused of opening a number of dummy bank accounts in 2011 in the name of dummy sarpanches (village headmen) and later the amount to the tune of Rs 1.15 crore was encashed by the PA.
The main opposition Congress has been pressing for dismissal of Ranike, who represents the Attari assembly constituency, from the state cabinet.
