The Narcotics Control Bureau (NCB), which arrested Arjun Rampal's girlfriend Gabriella's brother Agisilaos Demetriades, 30, questioned a film director on Monday.
The agency has now widened its probe to investigate further drug links. "We have questioned film director S Kohli as he has links with Demetriades," said a senior NCB officer. Kohli will be questioned again, sources said.
Demetriades will be produced before a court on Tuesday. "Demetriades's custody will be over on Tuesday and he will be produced before the court," the officer said.
The NCB has alleged that Demetriades is part of the drug syndicate and has been in touch with the other accused arrested in the case.
On the basis of information, a room at a resort in Lonavala was searched, where Demetriades was staying with his fiance, and 0.8 grams of small, round, black sticky substance, purportedly charas, was found. On Saturday, the agency had searched the Khar residence of the accused, where 1 strip of Alprazolam tablets was recovered.
The agency is investigating the source of these drugs. Demetriades's call data records are scanned for further investigation in the case.
The agency told a court that electronic evidence revealed that he was dealing in a variety of drugs, which needs detained investigation. "It is clear that Demetriades purchased contraband from accused Kaizan Ibrahim and Sandeep Gupta. Hence, he is part of the conspiracy for drug procurement," the agency had told court while seeking his custody. The agency has also found links with Dipesh Sawant and Samuel Miranda, who are linked with accused Showik Chakraborty, Rhea Chakraborty and late Rajput, as per the agency's prayer to the court.
