PROVIDENCE, R.I. (AP) — Talk show host John DePetro of WPRO-AM was sued Friday by a producer at the station who says he made unwanted sexual advances toward her.

Dee DeQuattro filed the lawsuit against DePetro and the station’s management and owner, Cumulus Media, in Providence Superior Court. DePetro’s lawyer says the allegations are false.

DeQuattro’s lawsuit claims the harassment started in May, when DePetro took her to a home in Barrington and made advances toward her. He apologized, but the lawsuit says his inappropriate, sexually charged behavior began again, which included showing DeQuattro pictures of women he found sexually attractive and asking her if he and another woman could have sex with DeQuattro and her boyfriend.

DeQuattro also alleges that after she complained to management, they failed to conduct a thorough investigation. The lawsuit says she was retaliated against after filing a discrimination charge with the Rhode Island Commission for Human Rights on Aug. 3, when the station locked her out of her email account and the station.

DePetro’s lawyer, Timothy Dodd, said his client is innocent and was not involved in any misconduct.

‘‘The allegations being made against him are false,’’ Dodd said.

WPRO and Cumulus Media did not immediately return messages seeking comment.
