A day after a military court ordered Indian Air Force Flying Officer Anjali Gupta's dismissal from service, a Court of Inquiry into her charges of sexual harassment against three senior officers has unanimously concluded she has 'failed to prove her complaint', IAF authorities announced on Friday.

"The three-member Court of Inquiry, headed by Air Marshal Bandopadhya, in its findings, has concluded it is the unanimous opinion that Anjali Gupta failed to prove her complaint of sexual harassment," IAF's Senior Personnel Staff Officer Ground Captain Ajay Masson and its legal officer, Wing Commander P C Prakash told a press conference.

'No action needs to be taken against Squadron Leader R S Choudhary, Wing Commander V C Cyriac and Commodore A Chopra, against whom Anjali Gupta has made charges of sexual harassment', the inquiry report concluded, they said.

The IAF officials, however, refused to comment on the status of the complaint lodged by the cashiered officer at the Vimanapura police station in the city, saying, "It is for the police to give update."

Masson sought to clarify it was incorrect to say that Anjali Gupta was the first woman IAF officer to face court martial  proceedings, as records point that some women officers have faced similar proceedings but refused to give details.

Despite giving ample opportunity by the Court of Inquiry, Gupta failed to make out a case, Masson said.

On Thursday, the General Court Martial sentenced Gupta to be cashiered on five charges, which included indiscipline and insubordination.
