The BJP members also demanded strict action against the culprits who had committed such an act and sought a statement from the government over the issue.
MLC Mahachandra Prasad Singh first drew the attention of the House towards the issue and pointed out that washing the statue was an act of insult to Manjhi, who hails from a 'Mahadalit' caste (the lowest among the Scheduled Castes).
"This is a very serious issue and a shameful one. All this is happening in the 68th year of Independence. The state government should answer why a Mahadalit is being insulted like this. They should also reveal what action has been taken on the issue," Bihar BJP President Mangal Pandey said in the House.
As the Chairman's appeal to the BJP MLCs to return to their seats fell on deaf ears, he adjourned the House till tomorrow noon.
Though he refused to reveal the name of the leader, he added the intentions of such forces would be defeated by the people in the coming state elections.
