Delaware State police are trying to identify the man who posed as a doctor and fondled three female patients.
It happened over a 2-week period at Christiana hospital.
The most recent case was two days ago on Thursday.
The phony doctor told each victim he wanted to do a physical exam, during which he improperly touched the women.
State police describe the man as dark skinned, under 6-feet tall with an average build.
He was wearing a white lab coat over a t-shirt and blue jeans.
Christiana hospital is also investigating, and reviewing card readers and surveillance pictures.
Anyone with information is asked to call Delaware State Police at (302) 834-2630.
