PHILADELPHIA (AP) — A 15-year-old Philadelphia girl has been charged in the death of her newborn son who was found in a dumpster.

Authorities say a woman approached some police officers on patrol around 10:30 p.m. Monday and told them she had found a baby that had been placed in the dumpster by her daughter's friend. The woman and the baby were taken to a hospital, where the infant was pronounced dead a short time later.

Officers then went to the home of the daughter's friend. The girl who had given birth and her mother were taken to a police building and the teen was arrested.

The girl was later taken to a hospital for what authorities said was "precautionary medical treatment," though further details were not disclosed.
