NPR podcast host Ramtin Arablouei has left the company following an internal investigation into allegations of inappropriate conduct.

Arablouei, co-host of NPR’s podcast “Throughline,” has been absent from the show for several weeks prior to his departure, which came after a formal complaint and internal review. The New York Times reported that Arablouei was accused of making an “untoward” compliment toward a female producer, telling her she was “a case for race mixing.”

According to the report, a subsequent investigation into his workplace behavior also found concerns about Arablouei oversharing details about his personal life. The female employee reportedly said she felt uncomfortable with how Arablouei would discuss his personal life during one-on-one meetings. She also alleged he flirted with podcast guests as well as another employee.

NPR attorney Ali Parker later informed the employee that her claims had been corroborated.

Arablouei joined NPR in 2015 and has worked as a co-host, producer, reporter, and writer for multiple podcasts. The investigation reportedly began in March after the employee filed a formal complaint.

“We take allegations regarding workplace conduct seriously and are committed to maintaining a safe, respectful and professional environment for all employees,” a spokesperson for the company told the outlet.

The spokesperson added that “any concerns raised through appropriate channels are reviewed carefully.”

NPR’s interim vice president of podcast strategy told staff: “We are working closely with the Throughline team on the show’s future direction and are grateful to Rund for continuing on as the show’s solo host.”
