WOODBRIDGE, Va. -- Police have arrested men accused of selling fake identification to illegal immigrants in the Prince William County.

Investigators said Carlos Lopez, Mario Peralto Alatorre and Jovani Hernandez Garcia used the Prince William Plaza shopping center in Woodbridge as a front. Police said the men sold IDs out of their car to anyone with cash.

"I can tell just by looking at all the financial records that we've seized that it's a long-term operation that they've been doing," said Detective Brian Wing of the Prince William County Police Department.

Investigators seized evidence including state and international I.D. cards, Social Security cards and other types of fake identification, News4 reported.

Detectives said the Prince William County parking lot bust was just the start of the investigation. Inside one of the suspects' homes, police said they seized a copier, computers and boxes of forged documents.

The fake IDs were sold for $100 to $200 apiece, and there was enough material to make more than 1,000 IDs, police said.

With all three suspects facing felony and misdemeanor charges, police said the fake ID ring has been shut down, but the investigation into whether there are more suspects and how many fake IDs are on the street continues.

"As far as the operation goes, it was a fairly decent sized operation. We haven't had one of this proportion in Prince William County before," Wing said.

The fake I.D. ring was so big that county police are asking the U.S. attorney general's office to make it a federal case, News4 reported.

With the anniversary of the Sept. 11, 2001, attacks just a few days away, police said the bust is especially concerning because any of the IDs could have been bought by someone planning to harm this country. Detectives said they are looking into that, but right now they said they believe most of the IDs were sold to undocumented immigrants.
