Authorities have confiscated more than $20 million in bogus bills, possibly a record counterfeit cache, and arrested a man they describe as the mastermind of the operation.

"This represents one of the largest counterfeiting seizures in the history of the United States Secret Service," said Richard J. Griffin of the Secret Service office in Los Angeles.Julio Antonio Marmol, 41, a native of Cuba who lives in Santa Ana, was charged Monday with two counts of possession of counterfeit money and dealing in counterfeit money, said U.S. Attorney Richard Bonner.

"The big fish has been caught," Griffin said.

Authorities recovered more than 20,000 $100 bills from Marmol's home, Griffin said. Printing plates, photographic negatives and other equipment were also seized.
