A Stoneboro man is in Mercer County Jail for allegedly stabbing his friend early Tuesday after an argument at a bar in the borough, state police said.

Police charged Brad Meade Quillen, 27, of 1151 Walnut St., with aggravated and simple assault, possessing instruments of crime and reckless endangerment.

Police said he stabbed Brian L. Hartman, 27, Stoneboro, in the leg at 1:45 a.m. at Quillen’s Cafe.

Quillen’s father owns the tavern, Stoneboro police said, and Hartman tends bar there. Police described the men as best friends prior to the argument.

The two were sitting at the bar drinking beer when they began arguing and Quillen pulled out a knife and stabbed Hartman, police said.

Quillen told police that he was holding a pocket knife and Hartman moved his leg into it, the affidavit said.

After the stabbing, Quillen ran out of the bar and into his apartment above it, according to the criminal complaint filed at District Judge Lorinda Hinch’s Mercer office where he was arraigned Monday morning.

Hartman was treated for a puncture wound at UPMC Horizon, Greenville, police said.

Quillen failed to post $5,000 bond Tuesday. He is scheduled for a preliminary hearing July 5 before District Judge Lawrence Silvis, Worth Township.
