WCSH-TV’s news director has left the station for unspecified reasons.

Maureen O’Brien left Channel 6 days after the station’s longtime weather forecaster went on the air to rebut rumors that he is among the suspected clients of an alleged prostitution operation in Kennebunk.

Steve Carter, the station’s president and general manager, would not comment Tuesday on O’Brien’s departure. He would not say why or when she left the position.

“It’s a personnel matter, and it’s not something we comment on,” Carter said.

He said he supported the decision to put Joe Cupo on the air to dispel rumors that he was a client of Alexis Wright of Wells.

Carter said he did not know who came up with the idea, but it was ultimately Cupo’s decision to be interviewed.

Cupo referred all questions to Carter.

O’Brien could not be reached for comment.

She became the station’s news director in September 2008, after working as managing editor for WCSH for five years, according to her profile on LinkedIn, a professional networking website.
