Pratyusha Banerjee's parents have written to Union Home Minister Rajnath Singh, demanding a Central Bureau of Investigation probe into the alleged suicide of the TV actress.

They had earlier written to Maharashtra Chief Minister Devendra Fadnavis requesting for a probe by Mumbai Police Crime Branch into her death.

In their letter to the CM, they have alleged that Pratyusha's boyfriend and actor-producer Rahul Raj Singh was "solely responsible for her death".

'...she fell prey to conman Rahul Raj Singh, who has not only cheated my daughter and is solely responsible for death, but also cheated many innocent girls like her to the tune of lakhs of rupees,' said the letter by Pratyusha's mother Soma Banerjee.

Rahul Raj Singh is out on bail.

The Balika Badhu fame actress was found hanging at her residence in suburban Goregaon in Mumbai on April 1. She was then rushed by Rahul to a hospital where she was declared dead.
