LOUISVILLE, Ky. (WDRB) -- Radcliff Police say they have arrested a man less than 24 hours after he physically abused a baby boy, then left him at his mother's house in a brutally beaten state.

According to an arrest warrant, it happened Thursday, Aug. 6.

Police say just before 7 p.m., they received a report that a man was seen hitting a child while traveling northbound on S. Dixie Boulevard, near W.A. Jenkins Road in a gold Mercury Grand Marquis. The witness was able to get a partial license plate number on the car, according to police.

The witness allegedly told police that the man was seen hitting a child in a car seat several times with his hand.

Police say they were able to match the partial license plate and car description to 35-year-old Daniel A. Cox, but were unable to locate the child.

A few minutes later, police say they received a report that a four-month-old boy was found unconscious at his mother's home on Franklin Court, near Independence Drive, in Radcliff.

Police say Cox was the father of the baby, and had dropped the child off at his mother's home, then drove away.

A neighbor who lives across the street from the mother says Cox didn't tell her he left the baby in the driveway and just drove off. When she realized what happened, she began screaming. 

"My baby's not breathing, oh my baby," said the neighbor. 

He says she came running across the street and asked if he knew CPR.

"The baby was just limp," said the neighbor. 

"During this time, the baby was not breathing and did not have a pulse," Radcliff Police say. "Cardiopulmonary Resuscitation (CPR) was started. Once officers arrived on scene, they continued CPR. The baby was then transported by Hardin County EMS to Hardin Memorial Hospital."

"Once at HMH, pictures of the baby were taken," police say. "Noticeable and major swelling was observed to the baby's head, left eye swollen closed, right cheek swollen, and major bruising to his back and to his buttocks. These injuries are consistent with a child being assaulted and abused."

Police issued a warrant for Cox's arrest just before 10 p.m.

Just after midnight, Cox was arrested by the Radcliff Police Department. He is currently charged with first degree Criminal Abuse of a Child Under 12, and according to online records, is being housed in the Hardin County Detention Center on a $100,000 bond.
