A reporter for a Spanish-language news outlet in Tennessee who has been detained by U.S. Immigration and Customs Enforcement was not shown any warrant when she was arrested this week, according to court documents filed by her attorney.

Estefany Rodriguez Florez, a reporter for Nashville Noticias who has done stories critical of ICE, was arrested Wednesday during a traffic stop, according to documents filed in federal court in Nashville. Her lawyer called for her immediate release, but ICE has asked a judge to deny the request.

Rodriguez, a Colombian citizen, entered the U.S lawfully and has been living in the country for the past five years, court records filed by her lawyer show. She has a valid work permit, and she has applied for political asylum and legal status through her husband, who is a U.S. citizen.
