He added, “it would be better if we don’t discuss it (the kidnap threat) here.” Sources said the letter also mentioned a ransom amount of Rs 2 crore.

Although it is not yet known if the Ganguly family, which stays in their traditional Behala house, has approached the police, both the relatives and the police have denied that any complaint was lodged in the matter. Ganguly’s elder brother Snehasish admitted that the letter had reached them. “Yes, there was a threat letter. We (family members) have discussed the matter and we do not think that the matter is alarming. We are not approaching the police,” said Snehasish.

Kolkata’s Detective Department chief Jawed Shamim said: “I don’t have any knowledge of such a letter. The Kolkata Police are not conducting any investigation in the case either.” SP (South 24 Parganas) Ajay Ranade said, “I don’t have any information about the letter.”

Dona and her father Sanjib Ray also refused to comment.
