Just after midnight on Wednesday, officers responded to a call in Richland Hills, Texas after a man told 911 operator that he carved a "pentagram" into his 6-year-old son's back for the "holy day."

The father, identified as Brent Troy Bartel, was eventually arrested and charged with assaulting his son on Wednesday.

The 911 call, made just minutes after midnight on 12-12-12, was as bizarre as the gruesome act itself.

"I shed some innocent blood," Bartel told the 911 operator.

"What do you mean, sir?"

"I inscribed a pentagram on my son," he replied.

"Why did you do that?"

"Because it's a holy day," the man said.

Here is an example of what a pentagram can look like:

During the same time, the boy's mother called 911 from a neighbor's house claiming that her husband was hurting their child.

Listen to both 911 calls via NBCDFW below:

When officers arrived at the Richland Hills home they found the 6-year-old in pajama pants, a large pentagram carved into his back. The carving actually covered the majority of his back, according to police.

More from NBCDFW:

Officers wrapped the boy in a jacket and turned him over to paramedics.  The child was transported to Cooks Children's Hospital for treatment.  Child Protective Services and a crime victim liaison are working with the boy and his mother.

Police said Wednesday afternoon that the carving isn't deep enough to require stitches and that the child is expected to be OK physically.

At the scene, officers also recovered a box cutter they believe Bartel used to make the carving.

Police arrested Bartel and charged him with aggravated assault with a deadly weapon.  He is currently being held on a $500,000 bond.

It is unclear whether the father got 12-12-12 confused with Dec. 21, 2012, which is the day that some believe the Mayans predicted to be the end of the world.
