DMK MP Kanimozhi and three others, arrested for their alleged roles in the 2G spectrum allocation case, moved the Delhi High Court on Saturday for bail.

Besides Kanimozhi, the three others who moved the high court against a special court order denying them bail two days ago, are DMK-run Kalaignar TV MD Sharad Kumar and Kusegaon Fruits and Vegetables Pvt Ltd directors Asif Balwa and Rajiv Agarwal.

DMK Supremo''s daughter Kanimozhi has been confined in Tihar Jail since her arrest on May 20. She was denied bail on Thursday by the trial court despite CBI not objecting to pleas for bail by her and four others.

Special Judge O P Saini denied them the bail saying the charges against them are of grave nature and the CBI's concession of not objecting their bail pleas was of "no consequence in the eyes of law".

The CBI had preferred not to oppose the bail pleas of Kanimozhi, Kalaignar TV MD Sharad Kumar, Kusegaon Fruits and Vegetables directors Asif Balwa and Rajiv Agarwal and Bollywood filmmaker Karim Morani, whose names had figured in the supplementary charge sheet filed on April 25.

The accused have been in the jail for last five to nine months.

Denying bail to Kanimozhi, the court had also rejected her plea for it on grounds of being a woman, saying that she "belongs to upper echelons of society and is also a member of Parliament" and cannnot be suffering on account of being a woman.
