Gregory Kostomite walked into Johnny B's Place in Upper Darby around 9 p.m. yesterday and, without a word, began punching a bar patron in the stomach, police said.
"Then, the people realized he was punching him with a knife," said Upper Darby Police Superintendent Michael Chitwood.
When other patrons at the bar on Garrett Road near Drexel Avenue realized what was going on, four or five of them tackled Kostomite and held him until cops arrived, police said. Meanwhile the victim, whose "bowels had been eviscerated," according to Chitwood, was rushed to Crozer Chester Medical Center, where underwent immediate surgery.
Initially listed in critical condition, the victim, whose identity has not been released, has since been upgraded to stable.
