STERLING HEIGHTS, Mich. (FOX 2) – A Detroit man used his title as a doctor to gain the trust of a 76-year-old woman. He then allegedly forced himself on her and began touching himself in front of her.

Dr. Stephen Mason, 54, was charged with assault and causing a public nuisance following the unwanted encounter earlier this month.

According to police, Mason met the 76-year-old woman through Facebook Dating. He is 22 years younger than her.

The two chatted and he offered to drive her to a hair appointment. His status as a doctor helped to make the offer attractive to the victim and she agreed.

After the appointment, she had him come to her home in Sterling Heights.

“She said, ‘Okay, let’s go to my house, we can hang out and talk for a bit,'” said Sterling Height Police Capt. Mario Bastianelli. “Then things went wrong. He went up to her and tried to force himself on her and started kissing her. She rejected the advances.”

When he was sent away, he began to masturbate in front of her, according to prosecutors.

“Eventually, he decided to take it upon himself and begin the satisfaction in her living room right in front of her,” Bastianelli said.

The elderly victim kicked Mason out and then immediately went to the Sterling Heights Police Department.

“I can’t stand to see this happen to another woman, so she did the right thing,” Bastianelli said. “She brought it up, and now he’s being held accountable for what he did.”

Mason is licensed to practice medicine in Michigan. He is listed on Google as a doctor in Southfield.

Police believe it is possible that there are other victims of Mason’s unwanted advances.

Mason is currently free on $1,000 personal bail.

“My warning is really: Be careful who you meet on social media,” Bastianelli said. “You never know who you’re going to meet. It could very well be a wolf in sheep’s clothing.”
