It has also been alleged that Nirav Modi possessed as many as six Indian passports. It is expected that a fresh FIR may soon be filed against him in this offence.

According to a report in the Times of India, the wanted diamond merchant avoided taking a flight from London, and instead travelled by rail instead. He travelled on an Indian passport when he took a Eurostar high-speed train from London to Brussels.

The report stated that the information was verified by Indian officials from European immigration authorities who captured his passport details on his trip to Brussels. Indian intelligence agency has now been tracing Nirav in Belgium.

In one of the passports, Modi had the full name written while the other only had his first name with a 40-week UK visa issued against it. It is probably the reason that he kept travelling to various countries, despite the government revoking his first known passport earlier this year, the sources told PTI

Both Modi and his uncle Nirav Choksi are said to have left the country before the criminal cases were lodged against them. It all started when Punjab National Bank (PNB) complaint against Modi and his uncle after the 13,000 fraud came to light. Modi allegedly cheated the nationalised bank in getting loans with the help of a few employees of the bank. The CBI and the ED have registered two FIRs each in connection with the case.
