BJP supporters led by district unit president Krushna Chandra Mohapatra and former minister Golak Chandra Nayak took out a rally at Udala and staged a demonstration outside the local police station demanding immediate arrest of the duo.
Later, they submitted a memorandum to sub-divisional police officer (SDPO), Udala, with an ultimatum in support of their demand.
Refuting the allegation as false baseless and fabricated, Soren has said it was an attempt to tarnish his image ahead of elections.
A 35-year-old divorcee had alleged in a complaint petition before the court on January 4 that she was raped by Soren and his associate when she had been to the MLA's house at Nuasahi-Nagpal under Udala police station to get back Rs one lakh she had paid for getting a job.
Meanwhile, additional superintendent of police, Bibhudendra Kumar Aich, who is the supervising officer in the case, said investigation was continuing and the statement of the woman taken.
IIC, Udala, Subrat Behera said medical examination of the woman was conducted in the sub-divisional hospital at Udala.
