Actor Arjun Rampal, who was summoned by the Narcotics Control Bureau for an appearance on Wednesday, has sought a week’s time before he appears before the agency in Mumbai, official sources informed. The 47-year-old actor said he is currently busy with personal matters, while seeking a week’s time. The NCB had summoned the actor for a second round of questioning in connection with a drug-related case. Fresh date for his appearance is yet to be announced. The development comes exactly a month after the NCB had grilled Rampal for nearly seven hours on November 13. The actor was quizzed by the agency after his Australian friend Paul Bartel was arrested in a drug-related case. Bartel was reportedly in regular contact with Agisialos Demetriades, an alleged drug peddler arrested by the NCB in October, and the brother of Gabriella Demetriades. (IANS)
