A 22-year-old Camden babysitter was arrested Saturday after police say she kidnapped a 4-month-old boy who was in her care.

According to Camden County police, Nadajia Hill began taking care of the young boy on Friday night, before allegedly boarding public transit to Newark, with the child alongside her. Then, on Saturday, police say, Hill boarded a southbound New Jersey Transit River Line train with the baby.

Police say the boy's mother reported him missing on Saturday morning after attempting to contact Hill and pick up her son.

Hill and the boy were located by police on the River Line train when it stopped in Riverside Township in New Jersey after 12:30 p.m. Saturday. The baby was found to be in good health and was returned to his family.

Hill was arrested and charged with kidnapping and child endangerment. She was remanded to the Camden County jail.
