U.S. Immigration and Customs Enforcement agents have responded to Maricopa County sheriff deputies' request to take custody of two suspected illegal immigrants in the Phoenix area.

Sheriff Joe Arpaio said Monday evening's encounter was the first between his deputies and federal officers since the recent Supreme Court decision to uphold part of Arizona's controversial immigration law, known as SB 1070.

Local law-enforcement officers have long had the authority to stop and detain illegal immigrants, including contacting federal agencies when it occurs.

The Supreme Court's decision included referring the case back to U.S. District Court in Phoenix for further action before the upheld part of SB 1070 takes effect.
