In another major sweep targeting illegal immigrants in the Las Vegas Valley, U.S. Immigration and Customs Enforcement officials said they rounded up 109 immigration fugitives in a six-day sweep that ended Tuesday.

Dubbed, Operation Return to Sender, the sweep for the most part netted Mexican nationals but it also included immigration violators from 11 other nations.

A statement from Immigration and Customs Enforcement says the arrests included 41-year-old Jesus Millan-Soto, a Mexican national with prior criminal convictions on weapons and narcotics charges who has been deported twice.

Federal authorities said they intend to prosecute him for a felony re-entry charge.

"Taking immigration fugitives off of our streets and restoring integrity to our nation's immigration system is one of ICE's (Immigration and Customs Enforcement) top priorities," the statement read, quoting Jim Hayes, field office director for detention and removal operations in Las Vegas and Los Angeles.

"Our message is, 'If you are ordered deported you should obey the immigration court's order. Otherwise, ICE is going to track you down and send you home.'" Hayes said.

Of those arrested in Operation Return to Sender, 87 were from Mexico; six were from El Salvador; five from the Philippines; two from Columbia; two from South Korea; and one each from Iran, Guatemala, Honduras, Nicaragua, Belize, Belgium and Cuba, according to ICE spokeswoman Virginia Kice.

Another six-day sweep in May, Operation City Lights, led to the arrests of 179 immigration violators in Clark County.

"One of the things we want people to understand is that these are going to be routine," Kice said by phone from Los Angeles.

"You can anticipate that we will see many more of these operations in the future," she said.

More than half of those arrested in Operation Return to Sender have criminal convictions ranging from drug violations and sex offenses to robbery and assault.

Of the 109 who were apprehended, 35 had been deported by Tuesday. The remaining 74 will appear before an immigration judge.
