Protests against the controversial Citizenship (Amendment) Bill continued to rock Assam as chief minister Sarbananda Sonowal was shown black flags in New Delhi on Tuesday evening.

Chief minister Sonowal was shown black flag by anti-CAB activists, the moment he was entering Assam House in the national capital.

Police personnel quickly swung into action and whisked the youths away from the spot.

Sonowal and finance minister Himanta Biswa Sarma were in Delhi on Tuesday to meet President Ram Nath Kovind and home minister Amit Shah.

Sources said two anti-CAB activists waived black flags at Sonowal as he entered Assam House.

Earlier, also Sonowal faced similar protests at different places in Assam, when the Centre had tried to pass the Citizenship (Amendment) Bill in the parliament.

The students of Cotton University and Dibrugarh University have already banned his entry into the campuses of the two universities.

On Monday, Sonowal had to ‘flee’ from Dibrugarh as AASU activists staged protest in front of his residence in the upper Assam town.
