Soon after his arrest, #StandWIthUmarKhalid started trending on Twitter.

Using the hashtag, senior Congress leader Shashi Tharoor tweeted, “PM says he welcomes criticism but forgets to mention the cost of criticism to be paid by those who speak out.”

Lawyer Prashant Bhushan, who was recently held in a contempt case, said Khalid’s arrest exposes the “malafide nature of its investigation into Delhi riots”.

Meanwhile, West Bengal Chief Minister Mamata Banerjee, who has been one of the most stringent critics of the BJP-led government, said that action should be taken if there is evidence of wrongdoing. Banerjee said those involved in “movements (against NPR, NRC) have been targeted (by the ruling party)”.
