Punjab National Bank on Saturday moved Hong Kong High Court against Nirav Modi, news agency ANI reports.
PNB will also approach the courts of other countries where Nirav Modi and Mehul Choksi have assets and businesses, reports said.
On March 23, the government had asked authorities in Hong Kong to arrest Nirav Modi suggesting it believes the fugitive is in the Chinese territory.
India's Minister of State for External Affairs V K Singh told parliament last week that "the ministry has sought the provisional arrest of Nirav Deepak Modi by the government of the Hong Kong Special Administrative Region (HKSAR), the People's Republic of China."
Regarding India's request, Chinese Foreign Ministry spokesman Geng Shuang on April 9 had told a media briefing here that "according to the one country two systems and basic law of the HKSAR, under the assistance and authorisation of the central government, the HKSAR can make proper arrangement on judicial mutual assistance with other countries," he said.
"If India makes relevant request to the HKSAR, we believe the HKSAR will follow the basic law and relevant laws and under relevant judicial agreements with India with the relevant issue," he said.
Billionaire Nirav Modi, his uncle Mehul Choksi and others are being investigated by multiple probe agencies after the scam recently came to light following a complaint by the PNB that they had allegedly cheated the nationalised bank to the tune of Rs
11,400 crore, with the purported involvement of a few employees of the bank.
The ED has registered the money laundering case against Nirav Modi, his firms and others on the basis of a CBI FIR.
The CBI and the ED have registered FIRs to probe the case and intensified the crackdown on Nirav Modi and Choksi with the ED seizing jewellery and assets worth thousands of crores of rupees, the I-T department attaching various properties, and the CBI grilling several senior executives of his company.
