Union minister Babul Supriyo on Saturday assured the mother of a student, who allegedly pulled the hair of the BJP leader at the Jadavpur University during his heckling on Thursday, that he will not harm the career of her son.

The student Debanjan Ballav's ailing mother Rupali had urged Supriyo "with folded hands" to pardon her son as handing him over to the police would ruin his career. "Dear auntie, don't worry. I will not take any action that will harm the career of your son," the minister said in a tweet on Saturday, and attached to it a newspaper clipping about the request of the woman who lives in Barddhaman town.
