Bond has been set for two parents charged with child endangerment after authorities found two children locked in a dog cage and two more smeared with excrement in a North Texas barn.

They were arrested on four counts of endangering a child, and Harkings faces an additional charge of one count of aggravated assault causing serious bodily injury, Akin said.
Initial reports quoted Akin as saying two children were found caged in the barn and two were found in the home. The agency did not say if the children have been placed together or split up.
Two adults whose children were found in deplorable conditions near Rhome, including two locked in a dog kennel, have been arrested and charged with felonies.
The children were taken to Cook Children's Medical Center in Fort Worth, but a hospital spokeswoman declined to disclose their conditions. The two oldest children were the ones locked in the dog kennel.More news: Dua Lipa very subtly calls out Grammy President in her acceptance speech
