A Pittsfield man has been jailed for stabbing a man early Sunday in a Youngsville establishment.

Jacob R. Sandt, 20, of Pittsfield, was charged with two counts of aggravated assault, simple assault, recklessly endangering another person, and disorderly conduct — fight, and taken to Warren County jail after failing to post $50,000 bail.

According to the affidavit for probable cause, the victim purchased drinks for a group of women that were at the bar with Sandt between 1 and 2 a.m.

“The defendant was angry that (the victim) bought drinks for his girlfriend and her girlfriends,” Youngsville Borough Police wrote in the affidavit.

The victim sat down with Sandt and spoke to him, according to police. He stood up and, as he began to walk away, knocked Sandt’s hat off his head, police said.

“That is when Sandt turned and stabbed (the victim) in the stomach area,” police said. “This caused others to react and get involved until the bartender started kicking people out.”

The victim was initially unsure of what he had been struck with, but was in a lot of pain, according to police. “When he pulled up his shirt and saw the blood he realized that he had been stabbed in the stomach.”

Police said the victim was treated immediately by a nurse, but did not seek treatment in a hospital until “a few days later.”

Sandt was arraigned Wednesday before District Justice Todd Woodin.

A preliminary hearing is set for 9 a.m. Wednesday, Oct. 24.
