This comes days after Swiss authorities froze four accounts belonging to Nirav Modi and his sister Purvi.
On the request of the ED, the high court directed the freezing of balance of $6.122 million (Rs 44.41 crore) in the account maintained in Singapore by Pavilion Point Corporation, a company owned by Mayank Mehta and Purvi Modi, it said.
The request by the probe agency was made on the ground that the money deposited in the account was illegally siphoned off from Indian banks.
