The baby boy was found in the women's restroom Wednesday morning at the McDonald’s on Rivergate Parkway. He was breathing and didn't appear to be injured.
Police said they believe the infant was about two or three hours old when he was found with his umbilical cord still attached.
Police said a man was seen taking the baby into the women's restroom before running out the door. Officers released a photo Thursday of the unidentified man taken from surveillance video.
“Of course we will treat him fairly, and again we just want to make sure the mother is safe and then find out the reason why what occurred yesterday – and again, each situation has to be evaluated independently,” said Michael Davis, with the Charlotte Police Department.
The baby was taken Wednesday to Carolinas Medical Center for observation.
