When I read about this news the first thing I thought about checking was:
Where will this exchange be located?
I went on the website and looked for their address and found this:
Cashaa is the trading name of Cashaa Technologies Limited, a UK registered company (No. 11644308) whose registered office is at Suite 207 Equitable House Business Centre, 10 Woolwich New Rd, London, England, SE18 6AB.
on google map i didn't see anything relevant about this address, but they reported this case to Cyber Crime department in Delhi

According to UK government site, they have registered their company in UK as well. I think they report to uk police.
