Ramtin Arablouei, co-host of the popular NPR podcast “Throughline,” has left the public radio network after it opened an internal investigation in March into his workplace conduct, according to two people with knowledge of the matter.
Arablouei has not appeared on new episodes of “Throughline” for several weeks, though neither he nor NPR has publicly addressed his absence. His departure followed complaints from a female employee on the show who alleged he behaved inappropriately toward her, including discussing details of his personal life during frequent one-on-one meetings, making offensive remarks in team meetings, and flirting with guests and a contract worker.
One specific allegation involved Arablouei commenting during a meeting that a producer was “a case for race mixing,” which some attendees viewed as an untoward remark about her appearance. The employee reported her experiences to a manager, who filed a formal complaint, prompting NPR’s internal investigation.

Any concerns raised through appropriate channels are reviewed carefully,” Walls said. “We are committed to maintaining a safe, respectful and professional environment for all employees.”
Arablouei did not respond to requests for comment.
The investigation began in March after the employee spoke with a manager. It remains unclear whether Arablouei’s departure was directly tied to the probe’s outcome.
Before co-founding “Throughline,” Arablouei contributed to several of public radio’s highest-profile podcasts. He helped create the hit business show “How I Built This” with Guy Raz and has worked on programs including “TED Radio Hour,” “Hidden Brain,” “Radio Ambulante,” and “Reveal.”
