Federal agents arrested 25 illegal immigrants after a two-day operation, customs officials announced Friday.

The Associated Press reports the arrests were made Wednesday and Thursday in Grand Island, York, Sutton, Gibbon, Hastings and Shelton.

Of those taken into custody, 15 are from Guatemala, eight from Mexico, one from El Salvador and one from Iran. U.S. Immigration and Customs Enforcement spokesman Tim Counts said the arrests were made in homes, businesses and other places.

Five of those arrested had criminal records other than immigration violations, including 43-year-old Salvador Rocha of Mexico, convicted in 1991 for smuggling illegal immigrants, 19-year-old Hugo Galaviz of Mexico, convicted of possessing burglary tools and a suspected gang member and 35-year-old Ruben Perez-Mora of Mexico, convicted of drunken driving in both Nebraska and Georgia.

Two others who were arrested were not named, but one had been convicted of marijuana possession and the other of a misdemeanor for failing to appear in court to face a petty assault charge.

All are being held in the Phelps County Jail.
