Mumbai: Film producer Firoz Nadiadwala was seen arriving at the Narcotics Control Bureau (NCB) office on Monday afternoon, a day after his wife, Shabana Saeed was arrested in a drug-related case.

The NCB summoned the veteran Bollywood producer in connection with the arrest of his wife and seizure of drugs from their residence. Firoz, who was not at home on when the central agency raided his Juhu premises, was summoned for further investigations.

The federal anti-narcotics agency has recovered 10 grams of ganja from Saeed's possession. She has been booked under sections 8c (produce, manufacture, possess, sell, purchase, transport, warehouse, use, consume, import or export of any narcotic or psychotropic substance), 20B ( punishment for producing, manufacturing, possessing, selling, purchasing, transporting or using cannabis), 27A (punishment for consumption of drugs).

"We have arrested Firoz Nadiadwala's wife under the Narcotic Drugs and Psychotropic Substances (NDPS) Act. Further investigation is on," NCB Mumbai zonal director Sameer Wankhede said in a statement.

"Firoz Nadiadwala's wife Shabana Saeed was issued a notice under section 67 of the NDPS Act. She was arrested after her statement was recorded," officials said.

Apart from Nadiadwala's wife, four other persons were arrested by the NCB last night during its raids at five places in Mumbai and Navi Mumbai. A total of 727-gram ganja, 74-gram charas, 95-gram MD and around Rs 3.50 lakh were seized from the four accused.

The operation is part of the ongoing investigations over the past three months to unravel the nexus between Bollywood and the drugs mafia, which emerged after actor Sushant Singh Rajput's death in June.
