Officials say they searched state and federal data bases to find 171 convicted sex offenders who were illegally in Virginia.
As a result, the offenders are being deported to Argentina, Bolivia, Germany, Laos, Mexico, Scotland and dozens of other countries.
At a news conference in Richmond on Wednesday, Virginia Attorney General Bob McDonnell announced the results of "Operation Predator." He was joined by Virginia State Police and leaders of U.S Immigration and Customs Enforcement.
The officials said the 171 offenders are either incarcerated and being processed for removal from the U.S. or already in federal custody.
Eighty-four offenders found in the search had already left the country or had been deported.
