Accusing the West Bengal government of "sleeping" while the child trafficking racket was active for so long, actor-turned-BJP MP Roopa Ganguly on Wednesday said those who are putting such "detestable charges" on her would have to pay for it.

"Those who are trying to put such detestable charges on me and a young girl like Juhi Chowdhury, would have to pay for it," Ganguly said, refering to her name being mentioned and BJP women's wing leader Chowdhury getting arrested in connection with the Jalpaiguri child trafficking racket.

"The home (adoption centre) was running for a long time. How come the state government was not aware of any of these activities? I hope they were not sleeping," she said.

The prominent BJP leader's name was dragged into the case after Chandana Chakraborty, one of the prime accused said Chowdhury, who took her to Delhi, "might have" talked to Ganguly about the adoption centre.

"I haven't talked to anyone, Juhi did. She might have talked to (BJP leaders) Roopa Ganguly and Kailash Vijayvargiya. I was sitting in a separate room," Chakraborty claimed.

Four people - ABJP district women wing (Mahila morcha) leader Chowdhury, Jalpaiguri-based child adoption centre Bimala Sishu Griho chairperson Chakraborty, Chief Adoption Officer Sonali Mondal and Manas Bhowmik - are already in custody for their alleged role related to the selling of at least 17 children through shady adoption deals.
