The Lancaster Township Police public information officer confirmed that investigators began to question the person just after 5:00 p.m. Friday.
Police approached the person near their vehicle somewhere in southern Lancaster County.
Meantime, the mother of the young victim told us Friday that she is just grateful her little girl is home alive.
"I can't explain the thoughts that go through your head, the terror," said Jaimee Smeal.
It was 2 1/2 hours of terror for Jaimee when her 5-year-old daughter disappeared Thursday evening from the front yard of Smeal's mother's home in Lancaster Township.
A massive search got underway. The last person to see Smeal's daughter was 6-year-old Nevaeh Rambler.
"Outside we were playing house," she said, "and she was pretending she was going to school, and she walked away."
Nevaeh never saw a car, but says she was scared after her friend disappeared.
Soon panic set in, and word spread through the neighborhood.
More than 2 hours later, 15-year-old Temar Boggs and his friend Chris became heroes when they spotted the girl nearby in a man's car on Betts Farm Drive.
They began following the car on their bicycles
"As soon as the guy realized we were chasing him, he stopped at the light and he let her out," said Boggs. "And she ran to me and said she needed her mom."
"I'm definitely grateful God was watching over her and brought her home," said Jaimee.
"I believe it took courage for them to follow the car," said Manheim-Lancaster Township Police Chief Neil Harkins, referring to the teenage boys. "The girl is here with us today."
Police say an assault did occur but won't release more information about the type of assault.
They also know at some point the suspect took the victim to get ice cream.
The girl's mother told Action News the girl was released from the hospital and was resting comfortably at home Friday afternoon.
Police say they have to be patient with victims of this age. It may take some time to sort out the details of exactly what happened.
Though police confirmed they are talking to a person of interest, there have been no suspects named and no charges filed.
