IIRC, the Dhruv has yet to achieve FAA or JAA certification so you are unlikely to see any working over here. I do, however, think that some have been sold to the Israeli military.
The Indian Air Force did bring some to Farnborough last year to display. There are photos in the 'ROTORHEADS AROUND THE WORLD' thread somewhere.
And although it 'looks' like an EC-145, it is considerably larger. About 2 tonnes larger, I think.

PS Try asking Google. Google knows everything!
Edited to add: Actually, before you ask Google, try asking PPRuNe! A search on 'Dhruv' will throw up a few previous references (including the Farnborough shots.)
