Rahul Mahajans, was interrogated throughout the week to reconstruct the events at the drug-laced party that killed an aide of his late father and Bharatiya Janata Party (BJP) Pramod Mahajan.

Investigators probing the death of Bibek Moitra and the brush with death of Rahul also uncovered suspected links between a Nigerian who allegedly sold the killer narcotics for the June 1 party and Bollywood personalities.

After letting Rahul sleep for some hours, he was again taken for questioning on Wednesday morning, police said as they readied to take him to his father’s 7 Safdarjung Road where the party took place.

Investigators say they have stumbled across information linking Nigerian drug peddler Abdullah, who allegedly sold the drugs to Sahil Zarru that eventually reached the Mahajan residence, with some film producers in Bollywood as well as designers and businessmen here who were clients.

Rahul is charged under Sections 21, 25, 27 and 29 of the Narcotic Drugs and Psychotropic Substances (NDPS) Act. If proven guilty the accused can be jailed for a maximum of 20 years and fined Rs 200,000 ($4,400).
