The Narcotics Control Bureau (NCB) questioned Arjun Rampal for around six hours at its Mumbai office on Dec 21. He was questioned in connection with psychotropic substances found at his home. Zonal director Sameer Wankhede said that the agency has found some contradiction in the prescription submitted by the actor to NCB. “There was a discrepancy in Arjun Rampal's statement. He can be called for questioning once again,” Sameer said. Last month, the agency had conducted a search at Rampal’s residence in Bandra. It seized electronics gadgets & some medicine restricted under the NDPS Act. NCB had already questioned Rampal and his partner Gabriella Demetriades in connection to the Bollywood drug case. On November 13, Rampal was questioned for nearly seven hours. Gabriella had also been called for two rounds of questioning by the NCB. Watch the full video for more.
