Eszter Vajda, the UNC-TV reporter at the center of a controversial documentary about Alcoa is no longer employed by the television station.

Vajda's employment ended at 5 p.m. Tuesday, said Gail Zimmermann, associate general manager of the station.

Zimmermann declined to discuss how or why Vajda's employment ended.

"It's a personnel matter and so I can't say anything about that," she said.

Vajda's involvement in a documentary about aluminum maker Alcoa has been the subject of news stories.

Alcoa is seeking to renew its federal license to operate hydroelectric dams on the Yadkin River. The state is fighting the relicensing, and wants to take over the operation.
