A three-day sweep by agents with US Immigration and Customs Enforcement resulted in 20 arrests in seven southern Indiana counties, including Vanderburgh.
The Jasper Herald reports that seven of the illegal immigrants were fugitives with outstanding deportation orders.
13 were found to be in the United States illegally.
Some of the illegal immigrants were picked up at their homes.
Agents also went to Farbest Foods in Huntingburg, the Wal-mart Supercenter in Jasper, and the YMCA in Washington.
All 20 detainees will be deported.
