The hand-written banner, claimed to be of the outlawed CPI (Maoist), was surfaced on the highway near Jambahali village under Madanpur Rampur police station limits in the district.
In the banner, the Maoists alleged that several girl students of the Shree Education College, a private-run college located at Tujung village under Madanpur Rampur block in Kalahandi district, have been sexually harassed in the institution and threatened to be killed if they would speak up in this regard.
The leftist-extremists also asked the authorities of the private-run college to provide safety and security to the girl students of the institution, failing which the authorities would get stringent punishment.
On the other hand, the principal of the college rejected the allegation and told Argus News that they would co-operate the police during investigation in this connection.
On being informed, Madanpur Rampur Police reached the spot and started an investigation into the matter.
Meanwhile, panic gripped the locals after Maoist banner was found in the village.
