The official said that Rampal has been asked to appear before the NCB team, which is investigating alleged Bollywood drugs after the death of actor Sushant Singh Rajput.
This is the second time NCB will question the model-actor in the case of drugs.
Earlier, he was questioned for nearly seven hours by the agency on 13 November.
The official said that Rampal was summoned on Wednesday while interrogating some people arrested by the NCB in the drugs case.
The NCB searched Rampal’s home in Mumbai’s Bandra area last month and seized electronic gadgets and some drugs banned under the Narcotic Drugs and Psychotropic Substances (NDPS) Act.
His partner Gabriella Demetriades was also questioned in the case by the agency for two days last month.
Based on some WhatsApp chats involving drugs, the NCB launched an investigation into alleged drug use in Bollywood following Rajput’s death in June this year.
The central agency had earlier arrested Rajput’s girlfriend, actress Riya Chakraborty, her brother Shobik, some employees of the late film star, and some others under sections of the NDPS Act.
Rhea Chakraborty, her brother, and some other accused were later granted bail.
