Police in Oregon are looking for more patients of a man they say practiced medicine without a license, including minor surgery and procedures on a living room couch.

Police in Redmond, Ore., say Scott Hanson, 22, was giving exams, dispensing prescription medication and even performing surgery without a medical license. His mother told ABCNews.com that the incidents have been blown out of proportion by police and the media.

Scott Hanson, 22, of Crooked River Ranch, was arrested Tuesday and charged with six counts of identity theft, second-degree assault, forgery, tampering with drug records and multiple counts of theft after one of his patients, a friend, realized he was not a doctor, as he had told her and his other patients.

He was also charged with six counts of recklessly endangering another person, third-degree sexual abuse, sexual harassment and various charges relating to possession of a controlled substance.

Redmond Police Capt. Brian McNaughton told ABCNews.com that police know of three patients but "absolutely" believe there are more.

"Who knows how sterile any of the instruments were," he said, noting that these people were at risk of infections, or worse. "If you were treated by this individual, seek professional advice as soon as possible."

"He was doing anything from treating people for infections to injury to minor surgery," he said.

An exam and prescription medication, which was dispensed on the spot, McNaughton said, would cost "patients" around $50. The surgical procedure -- there was only one police are aware of -- involved "maybe cutting off some skin and stitching things up," McNaughton said.

The charges of sexual abuse and harassment stemmed from one of his exams, McNaughton said, declining to further detail what led police to those charges.

But Hanson's mother, Renee Hanson, told ABCNews.com that police and the media have blown this up into something it's not.

"This is absolutely horrible, what the news has done," she said. "I'm so embarrassed. He's not performing multiple surgeries."

Renee Hanson said her son had planned to become a doctor, but that she didn't have the money to send him to medical school. Those plans, she said, are obviously over now.
