A New Jersey priest was arrested Friday after allegedly pointing a musket at an 8-year-old boy for rooting for the Cowboys, the Bergen County Prosecutor’s Office said.

Father Kevin Carter, of St. Margaret of Cortona Church in Little Ferry, was charged with endangering the welfare of a child and aggravated assault by pointing a firearm for a Sept. 13 incident — the NFL’s opening Sunday.

According to NBC 4 New York, the 54-year-old Roman Catholic priest approached the child before Mass and asked to see him in a rectory room. While there, Carter, a Giants fan, allegedly pointed a functional, Civil War-era musket at the boy, who reportedly was set to root for the Cowboys later that day, and threatened him.

“As he raised his weapon and pointed it at the boy, he said, ‘I’m going to shoot you,’ ” Bergen County Prosecutor John Molinelli told NBC 4 New York. “The young boy was apparently a fan of a particular football team, the priest was not. So perhaps we have indication it started out as that.”

The boy was unharmed.

Authorities told NJ.com the incident was seen by multiple parishioners, one of whom notified the archdiocese, who in turn notified the police.

According to the website, police later seized the weapon, as well as ammunition and gun powder, among other items. Carter, who has been with St. Margaret’s since February 2013, is being held on $15,000 bail.
