NEW DELHI: Two Delhi Police teams on Monday went to Twitter India offices to serve notices in connection with the probe into the alleged 'Congress toolkit' matter. Two teams of Special Cell went to Twitter India offices located in Delhi's Lado Sarai and Gurgaon, on the outskirts of the national capital. The police said that the visits were part of a "routine process". "This was necessitated as it was to ascertain who the right person was to serve a notice, as replies by Twitter India MD had been very ambiguous," said Delhi Police sources. Earlier it was reported that the police had raided Twitter India premises.
