GREEN BAY, Wis. (AP) -- A three-day sweep by federal immigration agents resulted in the arrest of 20 immigrants in eastern Wisconsin who had ignored orders for their deportation.

Officials say arrests were made in Brown, Door, Kenosha, Outagamie, Sheboygan and Winnebago counties, and they involved fugitives from El Salvador, Honduras, Jordan, Laos, Mexico, Nicaragua and Yugoslavia.

A dozen agents from the Milwaukee office of the U.S. Immigration and Customs Enforcement Department made the arrests over a three-day period starting last Friday.

Gail Montenegro of the department's Chicago office says the arrests are part of a nationwide effort to apprehend those who have gone before an immigration judge and been found to have no right to stay in the U.S. She says they'll stay in custody until they can be deported.

They're being held at the state's Dodge Correctional Institution.
