In surveillance video released by the Philadelphia Police Department, the suspect can be seen reaching down into a child's stroller as the mother's back is turned.
As the suspect leans his head down toward the child, the mother sees what's happening and wrenches the baby away.
Meanwhile, another patron in line shoves the suspect away before the suspect leaves the camera frame.
The Philadelphia Police Department's Special Victims Unit has called the case "peculiar."
"It’s actually a rather peculiar set of circumstances in we are actually asking for the parents or who we believe to be the parents to maybe come forward and give us a better idea of what happened out there," police said.
