Amid allegations of extortion of money from students in the name of admissions in Kolkata colleges, West Bengal Chief Minister Mamata Banerjee on Monday paid a surprise visit to Asutosh College here and warned of "strong action" against anyone indulging in irregularities during the admission process.

"I was also into student politics. I have spent nearly six-seven years of my student politics in this college. That's why I have come here to know the situation. So far, I have not received any complaint from the students or their guardians," said Banerjee, who was a student of the South Kolkata college. Banerjee said the students' unions should be "helping hands" for the students and make sure that those from poor families also get a chance to pursue higher education.
