Federal officials confirmed they arrested 107 people for immigration violations in Santa Cruz, Watsonville and Hollister in an organized sweep Thursday and Friday. Those arrested by U.S. Immigration and Customs Enforcement officers were foreign nationals with final orders of deportation, criminals and other immigration violators, spokeswoman Lori Haley said. Most were Mexicans, though some were from El Salvador, Guatemala and India, she said. "We know who we are going to look for," Haley said. "They have been ordered to leave by a judge and they are ignoring those orders." Nineteen arrested in the operation, dubbed Return to Sender, have criminal convictions including robbery, assault with a deadly weapon and sex offenses against minors, she said.
