The Delhi Police on Wednesday issued a notice to farmer leader Darshan Pal over the violence during the farmers' tractor rally on Republic Day, asking why legal action should not be taken against him. Noting that the vandalisation at the Red Fort on Republic Day was "the most deplorable and anti-national act", the police asked Darshan Pal to submit his response within three days. The action comes after Delhi Police Commissioner SN Shrivastava alleged that farmer leaders were involved in the January 26 violence and warned that no one will be spared.
