The Delhi Police's Special Cell on Monday served a notice to Twitter India in connection with the probe into the alleged 'Covid-19 toolkit' matter, with two teams descending on its offices in Delhi and Gurgaon, officials said.

"The Delhi police team went to the Twitter office to serve a notice to Twitter, as part of a routine process. This was necessitated as we wanted to ascertain who is the right person to serve a notice, as replies by Twitter India MD have been very ambiguous," Delhi Police PRO Chinmoy Biswal said.
