A couple of credit card theft cases involving people at medical facilities in north Fulton County have police wondering if the same person is behind both of them.

One case happened at WellStar North Fulton Hospital, according to Channel 2 Action News. The other was at a pediatric office across the street.

Alpharetta police said one of the victims was a man having surgery at the hospital.

"He informed us his credit card company notified him his card was being used at a Target to purchase over $400 worth of gift cards," Officer Jeff Ross said.

The patient left his wallet with his clothes in a bag while he had a procedure, police said.

A hospital statement to Channel 2 said, in part, “Unfortunately, theft in public places tends to increase during the holidays, and hospitals are not immune. We continue to be vigilant during this time.”

A few days later, Roswell police said a doctor at a pediatric office got credit fraud alerts after her card was missing.

A suspicious woman was reported in the pediatric office that day, matching the description of a woman police say used the hospital patient’s card.

"If the situation is ideal, you have a loved one that can come with you,” Ross said, “or you can leave your wallet at home with friends ... with someone you trust."
