New Delhi, August 11: Manipur Government today sent a formal request to the Centre today seeking a CBI probe into the "manipulative game" played by IOA and Sports Authority of India (SAI) to keep out weightlifter Monika Devi of the Beijing Olympics.

State chief secretary Rakesh on behalf of the government wrote a letter to the Union Secretary Satyananda Mishra, Ministry of Personnel and Public Grievances, seeking a CBI probe into Monika's doping charges.

A copy of the letter has also been sent to the CBI director, Aswhani Kumar.

Manipur Chief Minister O Ibobi Singh, who is camping here, also wrote a letter to Prime Minister Manmohan Singh today seeking his intervention in directing officials concerned to take up the matter (CBI inquiry) on a priority basis.

The chief minister had taken up Monika's case with the Prime Minister on Saturday in an effort to send the lifter to the Indian contingent in Beijing.

But the IOA had categorically said Monika could not join the contingent as all procedures were closed in Beijing.

Manipur Sports Minister, N Biren who is also camping in the national capital, said, "Anybody found guilty in the manipulating game and preventing Monika from participating in Olympics should not be spared".

The clearance for the lifter, who was dropped from the Indian squad for Olympics almost at the eleventh hour on July 6 after she had reportedly tested positive for an unidentified anabolic steroid, came from SAI on August 9 .

SAI provides samples for testing to the National Dope Testing Laboratory in New Delhi.

Monika has alleged "manipulation" in her samples collected on June 6 this year in Pune.

Monika's exclusion from the team became a major issue in Manipur with bandhs being called by public and sports associations threatening to pull out of upcoming national events.
