Bhubaneswar: The Orissa government on Tuesday ordered a probe into the alleged gang rape of a student in Sambalpur, after violent protests by students and residents forced the closure of a university.

The state government has ordered the probe and revenue divisional commissioner northern range would submit the inquiry report to the government within next 15 days, a top official of the office of Chief Minister Naveen Patnaik said.

The 20-year-old student of the Sambalpur University at Burla town, some 350 km from here, was found traumatised with multiple injuries at the nearby Sambalpur town on Sunday.

The first-semester student of Masters in Computer Application was missing after she reportedly left the university hostel for shopping on Saturday.

The police suspect she was abducted, administered drugs and raped. She also has several burn marks possibly caused by cigarettes, a senior police official said.

The university was closed indefinitely following violent protests by students over the alleged gang rape.

Hundreds of students on Monday ransacked several offices and damaged computers and university properties worth about Rs10 million (Dh909,000), a top official of the university said.

"Looking at the situation, we closed the university for the time being," Vice-Chancellor U.C. Biswal confirmed.

The protesting students blocked several roads, disrupted traffic in both Burla and Sambalpur towns on Monday and beat up two university officials, the police said.

The students also accused the police of failing to nab the alleged rapists. The students are accusing the hostel authorities of callousness. They said the authorities did not inform the police in time that the student was missing.

"The hostel authorities should have informed the police when the girl did not return to the hostel," student leader Hemant Meher said.
