Missing 5-year-old Nailla Robinson, the girl who was snatched from a Cobbs Creek, Pa., school Monday, was found safe in Delaware County overnight.

Robinson was found on a playground on 69th Street by a passerby, wearing only a T-shirt, according to Upper Darby Police Superintendent Michael Chitwood.

"This morning around 4:40 [a.m.] a fellow on his way to work heard screams for help, he was walking, he goes over to a playground area and finds a little girl hiding underneath the jungle gym," Chitwood told NBC10's Tim Furlong.

The man immediately called police.

Police tell NBC10 that she told them she was taken from school the day before and that she was cold and scared.

The little girl is at the Children's Hospital of Philadelphia for evaluation. Nailla's mom, Latifah Abdur-Rashid, told NBC10's Claudia Rivero that her daughter is preparing to be examined. She also says Nailla told her that she was blindfolded during her abduction. 

Now, police are looking for the person that took her from school Monday morning.

Nailla, a kindergartner at the Cullen Bryant Elementary School on 60th and Cedar Avenue, was allegedly snatched from the school around 8:50 a.m. by a woman claiming to be her mother.

The Philadelphia School District released a statement saying that the school didn't realize the girl was missing until Abdur-Rashid came to pick her up.

Nailla's family told NBC10 that surveillance video shows that a woman who appeared to be pregnant, wearing Muslim garb and going by the name "Tiffany" told school officials that she needed to take her daughter to breakfast. Then "Tiffany" signed Nailla out of school and walked away with her, according to the family.

"In the surveillance camera that the school has that I watched, she's dressed in traditional over-garment and Niqab," said Abdur-Rashid. "She has her face covered and only her eyes showing. She's wearing gloves. She's wearing all black. She has something white on her arm and she has a long black umbrella. The surveillance camera shows them walking through the hallway to get to the door. The next camera picks up and she's putting her umbrella up. Then they disappear."

Anyone with information on the incident is urged to call police.
