According to ED sources, Nirav Modi is currently in London on a Singaporean passport while his brother Nishal Modi is in Antwerp on a Belgian passport. Nirav's sister Purvi Mehta also holds a Belgian passport and is said to be in Hong Kong at present.
Purvi's husband, Mayank Mehta (of Rosy Blue Diamond) has got a British passport and is shuttling between Hong Kong and New York, the sources said.
The ED has issued summons to Nirav Modi's father Deepak Modi, sister Purvi Mehta and her husband Mayank Mehta. "They were sent the summons through mail," an ED official said on the condition of anonymity.
The PNB fraud was committed during 2011-17 by illegally issuing Letters of Undertaking (LoUs) and Foreign Letters of Credit (FLCs) and then rolling them over several times.
The ED official said that Nirav Modi's relatives were summoned in the first week of this month and were given 15 days to appear before it in the ongoing money laundering probe of over Rs 13,000 crore. The alleged banking fraud was committed by the diamond merchant, his group of companies -- Diamond R US, Solar Exports and Stellar Diamonds - along with his uncle Mehul Choksi and others.
Further notices would be issued to the three in case they fail to respond to the first summons, the official said.
Purvi is under ED's radar for her alleged role in round-tripping of Nirav Modi's laundered money via Foreign Direct Investment (FDI) back to India while her husband is suspected of supporting the diamond merchant in similar operations.
