“ICE’s primary immigration enforcement efforts target convicted criminal aliens,” said Daniel Bible, field office director for ERO in San Antonio. “Consequently, our operations improve overall public safety by removing these criminals from our streets, and ultimately from our country.”

Of the 153 arrested, 33 were presented to the U.S. Attorney’s Office to face criminal prosecution on charges of re-entry after deportation. The others arrested during the 12-day operation were being processed administratively for deportation.

The release stated that those who have outstanding orders of removal, or who illegally re-entered the U.S. after being deported, are subject to immediate removal. Those remaining in ICE custody will await a hearing before a federal immigration judge or are pending travel arrangements for removal.
