Meanwhile, the police said an investigation into the matter was underway.

Decrying the violence, the West Bengal party unit demanded upgrade of his security and said it would observe statewide condemnation day on Wednesday against it.

“I strongly decry the vandalism of Chowdhury’s residence. The cowardly act was perpetrated as a revenge for the way he has raised his voice against the Delhi riots,” state Congress chief Somen Mitra said in a statement.

Taking a swipe at the Centre, Mitra further said the law and order situation in Delhi was such that miscreants could freely attack even the residence of the Congress leader in the Lok Sabha.

Notably, Chowdhury has been a vocal critic of the Citizenship (Amendment) Act and has questioned the government on the contentious issue, time and again.
