A Chicago man was arrested after the weapon he was using to throw off his beer pong opponent accidentally went off.
According to DNAinfo, 27-year-old Manus Shannon was competing in the drinking game against a 24-year-old man at a Fourth of July party in Roseland last Saturday.
At around 9:20 pm, Shannon produced a 9mm semi-automatic pistol as his opponent was taking his turn.
Shannon reportedly waved the gun in his competitor's face in an attempt to impede his vision.
But the contender shoved Shannon backward, causing the weapon to discharge.
It hit his competition's finger as well as the shoulder of a 20-year-old man who was not playing but merely sitting nearby.
Shannon's rival and the other victim drove to Roseland Community Hospital where they were soon reported to be in stable condition.
Police went to Shannon's home later that night and arrested him for reckless discharge of a firearm.
He may face additional charges, however, because his FOID (Firearm Owners Identification) card and conceal-and-carry permit are for the state of Arkansas.
Shannon moved to Illinois last February but did not obtain the necessary documentation to carry a concealed weapon in his new home state, prosecutors said.
As of Monday, he was being held on $100,000 bail.
