EDISON - The FBI recently rounded up dozens of people allegedly involved in an ID scam, and authorities are calling the scam massive and sophisticated.

The alleged scam spanned from the Garden State to Guam. The group's purported ring leader, Sang-Hyun "Jimmy" Park, was among those paraded past cameras into the Federal Courthouse in Newark Thursday. Authorities say most of those rounded up are linked to a single complex criminal enterprise based in Bergen County's Korean community, but with a global reach.

Investigators say the ring worked out a scheme that boosted credit scores associated with stolen identities, so customers could then buy luxury brands such as Gucci, Rolex, Cartier and Lexus.

Authorities put the scam's financial toll in the millions. Retailers, banks and credit card companies are taking the biggest losses as a result. Fifty-three people now face criminal charges for their alleged involvement in the scam.
