Delhi Police had on November 27 last year registered a case of cheating and criminal breach of trust following an order from a court, which looked into allegations against the former IPS officer.
Police sources said they have not found any evidence to suggest that she misappropriated the money got as donation from Microsoft to impart computer training to paramilitary personnel.
After examining the documents of Bedi's NGOs, they said, they could not find any evidence to prove the allegations.
They said investigators are in the process of filing a closure report in the case very soon.
Reacting to the development, Bedi told PTI, "the only thing I want to tell you now is I am grateful."
A Delhi-based lawyer Devinder Singh Chauhan had alleged that she "looted" various paramilitary forces and police organisations in the name of imparting free computer training under the banner of her NGOs.
