A national spokesperson for the Congress, Priyanka Chaturvedi, received an open threat last week on Twitter of 'rape and murder like Nirbhaya'.
The abusive threat was a reminder of the chilling 2012 gang-rape and murder of a medical student in Delhi which had sparked a nationwide debate on women safety. It evoked bitter reactions on Twitter and the account was blocked. Ms Chaturvedi also filed a police case against the user.
Mumbai Police PRO, Sangramsingh Nishandar said, "Action will be taken according to law."
Speaking to a national media, Ms Chaturvedi said, "It's happened in the past as well. Last time too the person was arrested but he was freed soon since it's not a non-bailable offence."
Ms Chaturvedi also appealed for stricter laws against threats and abuses on social media in her blog.
