It was a big week for immigration-related arrests. The U.S. Immigration and Customs Enforcement agency has confirmed that a week-long special operation across the state resulted in 78 arrests.

The list of arrests includes many immigrants who had been incarcerated for serious crimes in the past. Field office director Henry Lucero announced on Friday that the operations in Phoenix, Flagstaff, Yuma and other parts of the state last week concluded with dozens of arrests of individuals with serious offenses like kidnapping, domestic violence, aggravated assault and drug trafficking. Almost 30 of the suspects arrested had DUI convictions on their records.

Lucero said the state is safer now that many of those arrested are in the process of being deported. Although the identities of those arrested were not made public, their nationalities include Mexico, Peru, Russia, Guatemala and El Salvador.
