Patna, Jan 07 (Agencies): Expressing reservations about the ongoing police probe in the Purnia BJP MLA Raj Kishore Keshari murder case, senior Congress leader Ranjit Ranjan, on Friday, said she would meet Prime Minister Manmohan Singh and Union Home Minister P Chidambaram seeking an inquiry by the CBI.

"In the given circumstances, a fair and honest investigation by state police is not possible," the former MP told reporters here citing the statement of Deputy Chief Minister S K Modi which gave a clean chit to the slain MLA.

She also said that such statement was aimed at influencing the probe and she would be leaving for New Delhi to request the Prime Minister and Home Minister to intervene immediately and order an independent inquiry by the CBI.

Disapproving reports that Rupam Pathak, the woman accused of stabbing the MLA to death, was 'mentally unfit', Ranjan said it must be probed what prompted her to take the extreme step.
