Jeffrey Tambor has denied allegations he sexually harassed a former assistant.
Amazon Studios has confirmed it is investigating a complaint against the Transparent star, just one month after executive Roy Price was forced to resign.
The investigation is reportedly centred around a claim made by Tambor's former assistant Van Barnes in a private Facebook post. The actor told trade publication Deadline the allegations are "baseless".
"I am aware that a former disgruntled assistant of mine has made a private post implying that I had acted in an improper manner toward her," he said.
"I adamantly and vehemently reject and deny any and all implication and allegation that I have ever engaged in any improper behaviour toward this person or any other person I have ever worked with. I am appalled and distressed by this baseless allegation."
Amazon has started speaking to members of Transparent's production team as part of the investigation. The show, created by nonbinary director Jill Soloway, recently released its fourth season and is not currently in production.
Amazon renewed the series for a fifth season back in August, but the latest iteration isn't expected to debut on streaming services until well into 2018.
Tambor plays the lead character, Moira, a transgender woman who comes out to her Jewish-American family. He was previoulsy well-known for playing George Bluth Senior in the award-winning comedy series Arrested Development.
Amazon Studios executive Roy Price resigned last month following claims he sexually harassed TV producer Isa Hackett. Former Disney executive Albert Cheng is at the helm of the $5 billion studio while the company searches for a replacement.
