RENO - Federal officials say 42 people were arrested around the Lake Tahoe Basin during a recent sweep by immigration agents.

Of those detained, 21 were immigration fugitives, meaning they had previously been ordered to leave the country by an immigration judge but refused to comply, Virginia Kice, spokeswoman for Immigration and Customs Enforcement, told the Sierra Sun newspaper.

Six of the detainees had previous criminal convictions.

The sweep took place June 30 and July 1 around the Tahoe area and were part of the Department of Homeland Security's Immigration and Customs Enforcement Fugitive Operations Program.

"The majority of those encountered during the operation have already been repatriated to their native countries," Kice said.
