On Friday, Arjun Rampal arrived at the Narcotics Control Bureau (NCB) for questioning. A source said that Rampal arrived at the NCB office around 11:10 am. He will be questioned about his contacts with drug peddlers and drug usage, sources said.

However, no evidence was found linking Gabriella with any drug peddler or drug nexus.

Besides, at least 20 persons, including actress Rhea Chakraborty and her brother Showik Chakraborty, several narcotics suppliers and drug peddlers have been arrested while some Bollywood personalities have been questioned. Rhea, however, had obtained bail.
