Sonia Gandhi's poster defaced outside Congress headquarters in Delhi

New Delhi, Jan.16 (ANI): Black ink was splashed across a poster carrying the image of Congress president Sonia Gandhi here on Monday evening, leading party activists to vigorously thrash and kick the culprit involved.

Congress supporters caught hold of the man, who identified himself as Tribhuvan Singh, and handed him over to the police. He is being interrogated.

The incident follows a similar attack on yoga guru Baba Ramdev on Saturday.

Angry over the yoga guru's remark that the 2008 Batla House shootout was not fake, a man threw black ink on the latter's face during a press conference in New Delhi. (ANI)
