Indiana State Police arrested a mother and father after five of their children were found in the back of a box truck along Interstate 70 Wednesday night.

Police said they were alerted by an anonymous tip from someone who said their relative had left Pennsylvania earlier in the day Wednesday with their seven children.

The caller told police they believed at least five of the children were riding in the storage area in the back of the truck.

41 year old David K. Detzen, and 40 year old Rebecca S. Detzen, of Fairmount City, Penn., were taken to the Henry County Jail on preliminary felony neglect charges.

The rented moving truck was found at a Flying J truck stop in Henry County, near the 123 mile marker of I-70.

Police said two small children were in the cab of the truck with their mother and father, but an 18-year-old daughter and four other children ranging from age 9 to age 17 were in the unheated back of the truck.

Police said there were also 18 cats found in the back of the truck.

Police said there were sleeping bags in the back of the truck, but the children had no heat or ability to communicate with their parents.

All of the family's belongings were also in the truck, and police said two of the children were riding on a tall stack of boxes.

Police said the children are with Child Protective Services and Henry County Animal Control took possession of the cats.
