Sonalika Mohanty has been claiming to have married Pradhan secretly three years ago but the MLA has rejected her claim and denied her allegations of harassment against him.
The woman reached the main gate of the assembly when the House was adjourned and attempted to end her life by consuming phenyl, a chemical used as household disinfectant.
She was rushed to Capital Hospital and is under treatment.
On May 17 she had trespassed the legislator's quarters at the MLA colony here by scaling the locked gate. Prior to that she had staged a dharna in front of his house at his native village in Angul district.
This apart, she had lodged a complaint against the lawmaker with National Commission for Women (NCW) too in this regard and also registered a case against Pradhan at the SDJM Court here in May this year.
