PHILADELPHIA (WPVI) -- Authorities are searching for a suspect who led police officers on a chase from Philadelphia into Delaware County Monday night.
The pursuit started around 8:30 p.m. near Tyson and Torresdale avenues in the city's Tacony neighborhood.
The suspect led officers onto I-95 and eventually out of the city.
Chopper 6 was overhead as the suspect's vehicle began sparking on the highway during the daring escape.
Around 9:30 p.m. the door of the vehicle opened up near the St. Davids exit of the Blue Route. Someone then exited from the driver's seat and ran into the woods near the train overpass on I-476 between Archbishop Caroll and Villanova University's tennis complex.
After the suspect ditched the vehicles, officers continued the pursuit on foot with flashlights and canines near the Villanova train stop.
It's still unclear why officers were chasing the suspect.
Just after 11 p.m., Radnor Township police said they were assisting Philadelphia and state police with a foot pursuit.
They said the agencies were clearing the scene.
No arrests have been made.
Although the suspect remains at large, Radnor Township police said there is no threat to public safety.
Anyone with information is asked to call police.
