At least a dozen patients of Tarek L. Haw plan to seek criminal charges against the former Coeur d'Alene doctor poised to lose his medical license for actions that include misuse of prescription drugs, insurance fraud and sexual misconduct, a lawyer representing the women said Friday. Rami Amaro, a Coeur d'Alene lawyer, said she initiated a police complaint that could lead to felony charges of sexual exploitation by a medical care provider. Ron Clark, a Coeur d'Alene Police Department detective, confirmed that an investigation has been opened but said he could not discuss the ongoing case.
