The demonstrators also presented a memorandum to Governor SC Jamir, seeking free treatment for the girl in a reputed private hospital in Bhubaneswar, a judicial probe into the incident, release of her medical report and Rs 50 lakh compensation.
The party workers vowed to continue their stir till the 14-year-old survivor gets justice.
The minor girl from Musaguda village of the district was allegedly gangraped by four men on October 10. In her statement to the police, she had claimed that the accused were in combat uniforms.
"The girl, a Class IX student, is under pressure from the police to change her statement. Her relatives are also being harassed by police," he said.
The former MP said they would hold another protest in Delhi on November 13 to seek justice for her.
"The survivor has clearly said that she can identify the accused, who she claimed were in combat uniforms. No step, however, has been taken by the police to arrange for a Test Identification Parade," said senior Congress leader and former Union minister Srikant Jena.
