Kolkata: Union minister Babul Supriyo was shown black flags and was allegedly heckled by a section of students at Jadavpur University (JU) in Kolkata. He was visiting the place to address a seminar organised by Akhil Bharatiya Vidyarthi Parishad (ABVP) - the student wing of the RSS.

Supriyo was initially stopped from entering the campus for around one-and-half hours by members of two Left-leaning organisations - Arts Faculty Students' Union (AFSU) and Students Federation of India - (SFI), who chanted 'Babul Supriyo Go Back' slogans.

The BJP leader faced another round of protests while trying to leave the campus around 5 pm.

Sources say he is currently held up at the campus, with protesting students blocking the way to his car.

"I did not come here to do politics. But I am saddened by the behaviour of some of the students of the university, the way they have heckled me. They pulled me by my hair and pushed me," Supriyo, who attended the seminar amid heavy security, told reporters visiting the campus.

Describing the behaviour of the agitating students as "absolutely deplorable", he alleged that the protesters were trying to "disturb peace" at the institute by "instigating the students and seminar organisers to create a stampede-like situation".

Supriyo also claimed that the protesting students tried to "provoke him by openly calling themselves naxals".

Sources said JU Vice Chancellor Suranjan Das, who rushed to the spot on being informed about the incident, tried to reason with the agitating students, who refused to budge from the main entrance of the university.

"It is unfortunate. I will send a report of the incident to the Governor, who is also the chancellor of the university," Das said about the incident.
