Police say 34-year-old Natia Dandy and her son Kanief of Philadelphia were found unharmed at a train station in Lancaster.
It is not clear where Dandy was heading.
Kanief will be turned over to DHS. Natia will have to answer to Philadelphia police.
An Amber Alert was issued Thursday afternoon after police say Kanief was abducted by his mother.
Police say Natia was at DHS on a scheduled supervised visit when she fled the building with her son.
The DHS tells Action News there was 'good reason' for Kanief to be removed from his mother's care.
Action News has learned that Natia Dandy has a history of mental illness and was thrown out of a homeless shelter earlier this week for violent behavior.
