Authorities have arrested the mother of a baby who was buried alive near a Southern California bike path.

Los Angeles County Sheriff's Sgt. Bob Boese said Sunday the woman was arrested late last week. He declined to release the woman's identity, citing the ongoing nature of the investigation.

Boese said tips from the public and media coverage of the baby's rescue led to the arrest.

The girl was believed to be 24 to 36 hours old when she was found Nov. 27. Two sisters walking on a bike path near a riverbed in Compton heard the child's cry.

Two deputies found her wrapped in what appears to be a hospital blanket, buried in a hole under loose dirt and piece of asphalt. She was taken to a hospital in stable condition.
