A teacher at Siliguri College has been accused of assuring a student of his department that he can help her get more marks in the undergraduate final exams against a payment of Rs 10,000.

An audio clip containing the bribe demand has been circulating in social media.

The accused teacher, however, denied the allegations. “I am not involved in this incident. Some people with political agenda are trying to frame me,” said the teacher.

The North Bengal University, to which the college is affiliated, started a probe and plans to file a police complaint.

Sources said vice-chancellor Subires Bhattacharyya had asked registrar Dilip Sarkar to start proceedings against the teacher.

“We have started a probe and will file a police complaint,” the registrar said.

In the audio clip, the teacher is heard asking the girl to pay him Rs 10,000.

“The teacher was heard saying that if she wanted to pass her exam with good marks, she should visit his house and pay him the amount with a copy of her admit card. He also said he had contacts with those people at the varsity who manage marks and everything,” said a faculty member of Siliguri College who heard the clip.

On Friday, the student sent a written complaint to the college authorities, confirmed Jayanta Kar, president of the governing body of Siliguri College.

“The student has sent an email to the principal and furnished all details of the communication in it. She mentioned that she had spoken to the head of the department of her course and furnished the faculty member’s phone number. It has nothing against the college but it is the name and fame of the varsity as the teacher was heard saying that he had connections with those who are associated with the exams and allocation of marks,” said Kar.

Sujit Ghosh, the college principal, said: “It is astounding to hear such an audio where a teacher is asking for money from a student. We are looking into the issue and if found guilty, the teacher concerned will face appropriate steps.”

A leader of the Trinamul Chhatra Parishad said the faculty member had even mentioned his residential address to the student during the communication.

“We will hit the streets in a day or two, demanding action against the teacher,” he said.
