Police say a fight broke out inside before the stabbing, forcing officers to evacuate the business.

PITTSBURGH —

A man was taken to the hospital in critical condition after a stabbing on Pittsburgh’s South Side shortly before midnight Friday.

Pittsburgh police said South Side entertainment patrol officers found the victim with a stab wound at the intersection of South 14th Street and East Carson Street. Officers provided aid until medics arrived, and Pittsburgh EMS transported the victim to a hospital.

Police said preliminary information indicates a fight broke out inside Capo’s Bar. Officers evacuated the business while the scene was secured. The Mobile Crime Unit responded to process the scene.

The investigation is active. Police are working to identify suspects and witnesses. Authorities have not released the victim’s identity or announced any arrests. Capo’s had advertised a Halloween costume party for Friday night on social media.

Capo’s previously reached agreement with DA’s office

The stabbing comes about two months after Capo’s, and the Allegheny County District Attorney’s Office reached an agreement that allowed the bar to remain open under court-ordered conditions. The DA’s office had filed a nuisance lawsuit, citing more than 40 reported incidents at the establishment, including allegations of fights, drug and gun possession, and inappropriate behavior by security guards. The office said it could ask a judge to shut the bar down if the conditions are violated.

Police have not said whether the stabbing is connected to the earlier lawsuit or whether it could affect the court-ordered agreement.
