"The agency has approached Interpol to issue RCN against Nirav Modi's brother Nishal, who is a Belgian national, and his executive Subhash Parab," said a Central Bureau of Investigation (CBI) official.
The agency's action comes two days after it sent a request to Interpol to issue a RCN against Nirav Modi and his uncle Mehul Choksi of the Gitanjali Group.
A Red Corner Notice is a request to locate and provisionally arrest an individual pending extradition. It is issued by the General Secretariat at the request of a member country or an international tribunal based on a valid national arrest warrant.
The CBI has named Nirav Modi, Nishal and Parab besides 18 others in the first charge sheet that it filed in a Special court in Mumbai on May 14 in the case.
The CBI has also named PNB's former MD Usha Ananthasubramanian in its chargesheet in the scam.
The CBI, in its first chargesheet had alleged that Nirav Modi, through his companies, siphoned off funds to the tune of Rs 6,498.20 crore using fraudulent LoUs issued from PNB's Brady House branch in Mumbai. Meanwhile, Mehul Choksi allegedly swindled Rs 7080.86 crore.
Nirav Modi left the country along with his family in the first week of January, weeks before the scam was reported to the CBI.
His wife Ami, a US citizen, left on January 6 and uncle Choksi on January 4.
