All four people accused of cheating the Punjab National bank to the tune of Rs 11, 400 crores were sent to police custody on Wednesday.
A special Central Bureau of Investigation (CBI) court here sent all the four, including celebrity jewellery designer Nirav Modi's Firestar Diamond President Vipul Ambani, to custody till March 5.
Security agencies have been cracking down on the properties of Nirav Modi and his uncle Mehul Choksi, but have been clueless about their whereabouts ever since the scam unfolded.
