National Public Radio, in collaboration with the Center for Investigative Reporting, will broadcast tonight the first in a three-part series on foreigners who work as confidential informants.

CIR reporter Andrew Becker along with Michael Montgomery, a producer with CIR’s California Watch project, produced the third story in the series about an informant who went public with his case last summer after immigration officials tried to deport him. The story will air Saturday, Feb. 13 on NPR’S Weekend Edition program.

The Los Angeles Times will run a separate story on the treatment of such informants.

CIR’s 10-month investigation on the treatment of informants who do not have legal immigrant status in the United States found several instances of informants who say they have been wronged by drug agents and immigration officials.
