A fight on the southbound Blue Route turned violent Sunday evening when a man pulled out a knife and stabbed another person in the stomach, setting off a police chase that ended in a crash and Villanova University locked down for roughly an hour.
The confrontation began around 5:35 p.m. Sunday in the southbound lanes of I-476 approaching Exit 13, straddling the line between Radnor Township and Lower Merion Township, according to NBC10 Philadelphia. Police received reports that the suspect was armed with both a gun and a knife, the station reported, though it was the knife he used to stab the victim in the stomach during the altercation.
After the stabbing, the man ran off on foot toward the Radnor Township area before getting into a vehicle and driving away, at which point Pennsylvania State Police took up the chase. Lower Merion Township police officers joined the pursuit as it unfolded, and the chase eventually led to a crash at Pennswood Road and Montgomery Avenue in Lower Merion Township, sources told the outlet. A Lower Merion police officer involved in that crash was not injured, per the same account.
Villanova Campus Locked Down as Chase Closed In
As the pursuit moved through the area near Villanova University, campus officials issued a shelter-in-place alert warning students and staff to stay put. Villanova relies on its Nova Alert emergency text system to broadcast exactly this kind of immediate lockdown notice when law enforcement activity threatens to spill onto or near campus grounds, according to the university's own security materials. Villanova public-safety officials also addressed the alert.
Police captured the suspect around 6:30 p.m., according to the school, and Villanova subsequently lifted its shelter-in-place order. Two people involved remained in custody afterward in connection with the stabbing on I-476, though authorities had not released their identities as of the report from the station.
Investigation Details Remain Limited
Pennsylvania State Police confirmed they were handling the investigation but did not provide further detail beyond that confirmation, the article notes. Police also had not revealed the condition of the stabbed man, leaving his medical status unknown. The exact circumstances that sparked the roadway fight in the first place have not been disclosed either.
The stretch of highway where the incident unfolded is no stranger to violence or heavy traffic. Interstate 476 carries more than 100,000 vehicles daily through Delaware and Montgomery counties, according to reporting by PhillyVoice that cited WHYY. That volume, combined with active construction, raises the stakes whenever a violent incident or high-speed chase breaks out along the corridor. A five-county regional figure put the number of aggressive-driving crashes in 2022 at 1,342, providing broader context for the dangers associated with roadway confrontations.
Ongoing Roadwork Adds Another Layer of Risk
PennDOT is in the middle of a $63.7 million project to resurface and repair nearly 17 miles of I-476, including ramps and bridges, running through Radnor Township between I-76 and I-95, as Hoodline reported when the work was first announced. That construction followed an earlier Active Traffic Management upgrade the state began in June 2024, installing electronic queue detectors and variable speed limit signs along 14.1 miles of the highway between Route 30 and I-95, per the Commonwealth of Pennsylvania — a system designed to cut down on sudden stops and secondary crashes during exactly the kind of highway emergency that unfolded Sunday. According to PennDOT District 6, roadway construction continued at night under two I-476 improvement projects in Delaware and Montgomery counties as of June 28, 2024.
Sunday's episode is not the first time the Blue Route has seen extreme violence play out at highway speed. In March 2024, a 62-year-old driver was arrested on northbound I-476 near mile marker 12 in Radnor Township after opening fire on another vehicle carrying a father and child, causing a multi-vehicle crash, according to FOX 29 Philadelphia. And in April 2025, a separate stabbing on the 100 block of Hillside Circle in Villanova sent a victim to a local trauma center, as previously reported by CBS News Philadelphia.
What Comes Next
Under Pennsylvania law, aggravated assault involving a deadly weapon can carry different grades depending on the specific conduct. Fleeing or attempting to elude police can be graded as a third-degree felony in qualifying circumstances under the state's vehicle code. It remains unclear what formal charges, if any, prosecutors have filed against the man in custody.
Pennsylvania police officers reported a total of 2,718 pursuits in 2022, according to the PA Police Pursuit Reporting System. According to the PA Police Pursuit Reporting System, the detailed information collected from pursuit reports is used to identify factors that influence the outcomes of vehicular pursuits.
Pursuits like Sunday's raise broader questions about police chases statewide. For now, key questions remain open: the motive behind the highway fight, the stabbing victim's identity and condition, the full extent of the Lower Merion officer's injuries, and whether formal charges have been filed against the suspect.
