UNDATED -- U.S. Immigration and Customs Enforcement agents Friday arrested 63 employees of a Bay Area Mexican restaurant chain for being in the country illegally.

Employees at 11 Taqueria El Balazo locations were taken into custody to be photographed, fingerprinted and processed, according to immigration agency officials.

One of those arrested was from Guatemala and the remaining were from Mexico, said officials.

Ten men and one woman were released today on humanitarian grounds pending future immigration proceedings.

Many of those remaining in custody were expected to be released under supervision while they wait for an immigration hearing. Others, including those with prior criminal convictions or deportations, were to be transferred to detention facilities.

Family members of those arrested can call (415) 844-5381 for information in the status of their relatives.
