Cops swung into action after several BJP workers tried to break barricades outside the minister's house which has been witnessing heavy deployment of police in the last few days. They were later taken away to the Parliament Street police station. Mr Bansal's residence, incidentally, is right opposite the BJP headquarters at Ashoka Road in Delhi.
The opposition, led by the BJP, has threatened of continued disruptions in Parliament if Mr Bansal is not sacked. On his part, the minister insists that he is innocent, having told seniormost members of the Congress, including the Prime Minister, that he has no business links with his nephew, who has been the genesis of this bribery scandal.
Mr Bansal's nephew, Vijay Singla, was arrested last week, allegedly accepting a bribe of Rs 90 lakh to help a senior railway official land a plum post in the Railway Board.
The minister has offered to resign but his party has, for the time being, decided against asking him to go.
