A Butler Township man is jailed on $100,000 bail on charges he threatened to kill a Butler police officer and the officer’s family.

Orion A. Kobet, 25, was arrested late Tuesday night in the 100 block of North Main Street where police were called for a four-person fight.

Officers broke up the fight shortly after 11 p.m. that had started as an argument between two of the combatants at the West New Castle Street Plaza.

But even after everyone was separated, according to court documents, Kobet kept trying to get at one of the other fighters.

The defendant became loud and profane after police arrested him. He allegedly threatened to kill one of the officers once he gets out of jail.

At the police station, Kobet “threatened that he was going to look me up in the phone book and kill me and my whole family,” the officer said in a police affidavit.

The defendant at one point claimed he was going to kill every person in the phone book with the officer’s last name “in the hopes they were related to me,” the officer said.

Kobet was arraigned Wednesday on a felony charge of aggravated assault and misdemeanor charges of terroristic threats and disorderly conduct.

He remains in the Butler County Prison while awaiting his preliminary hearing at 10 a.m. Monday.

Police, meanwhile, cited the other three people in the initial fight. Charged with summary disorderly conduct was Nathan D. Shea, 22, of Butler; Tiana T. Gladkoff, 18, of Butler; and a 15-year-old boy, who police did not identify.
