Pradeep Todi, brother of Kolkata-based industrialist Ashok Todi, on Tuesday underwent a lie detector test in Kolkata on Tuesday in connection with CBI prone into the death of computer graphics teacher Rizwanur Rahman who had married his niece Priyanka.
Pradeep, summoned along with his elder brother, is the first in the Todi family who was subjected to lie detector test as CBI wanted to ascertain the veracity of his replies to the allegation that he had paid Rs 11 lakh for separating his niece with Rehman.
The polygraphic test of Pradeep was carried out after his questioning for nearly three hours on Monday.
The report of his polygraphic test would be ready in a week's time, the sources said, adding a similar test on Ashok Todi, the main accused in Rizwanur death case, could not be carried out due to his ill health and the recent surgery.
Besides Todi, two others including Papu, who allegedly took money to break up the marriage between Rehman and Priyanka, were questioned by the CBI which is preparing to wrap up its investigations into the case.
Papu, who acted as a go-between for handing over the cash, would be subjected to lie detector test very soon, the sources said.
While it was turning out to be a case of suicide the victim had been forced to take the extreme step allegedly at the behest of the close kin of Priyanka's family.
Last month, the CBI had registered a case against Ashok Todi and others under section 302 (murder) of Indian Penal Code.
Priyanka had married Rizwanur in August this year against the wishes of her family and about a month later, he was founde near a rail track in Kolkata.
