A Highland Falls man was slapped with a felony after threatening his son's teachers with violence "worse than Sandy Hook," the Highland Falls Police Department said.

Administrators at the Highland Falls Intermediate School, a middle school for kids from fifth to eighth grades, called Timothy A. Doherty on Friday afternoon to tell him his son had been involved in a scuffle, cops said.

Doherty didn't take the news well, police said, and allegedly mixed in racial slurs with a threat to carry out violence at the school.

"If those (racial slurs) touch my son again, I'm gonna come down there and it's going to be worse than Sandy Hook," Doherty allegedly told school officials. "There's gonna be blood."

The 50-year-old man's threats prompted school administrators to call cops immediately. Police said they searched for Doherty and went to his home, and were unable to find him until Doherty turned up at the Highland Falls Police Department a few hours later and turned himself in.

Police charged Doherty with making a terroristic threat, a felony, and misdemeanor aggravated harassment. A judge also issued an order of protection, prohibiting Doherty from contacting or approaching the student involved in the school fight with his son.

Doherty was arraigned and released on $1,000 bail. He's due back in town court on April 25. It wasn't clear if Doherty had retained an attorney. A voice message was left on his home answering machine early on Saturday afternoon.
