Cop-on-Cop Confrontation in Philly Suburb (Unedited)

In a bizarre territorial dispute, police officers from neighboring towns in Pennsylvania began brawling while a woman lay injured on the ground nearby, MyFoxPhilly.com revealed Thursday.

Newly released video of the fracas shows officers from the Colwyn and Darby boroughs of Delaware County arguing over which police force should have responded to the incident.

The confrontation happened last Friday when an officer from Colwyn arrested a man on the street who allegedly punched a woman in the face. The cop had crossed from Colywn into Darby to respond to the incident.

Officers from both boroughs -- including Darby's police chief -- soon arrived on the scene. The chief began arguing with the Colwyn officer, who was sitting in his patrol car.

On the video, other Darby officers can be heard trying to calm the chief down. But the argument escalates.

The chief shouts, "Get out of Darby," as the Colwyn officer gets out of his patrol car and then has to be restrained.

Meanwhile, the victim lays on the ground as emergency crews work on her.

Former Darby Mayor Paula Brown told myFOXphilly.com that the Darby police chief had created a territorial atmosphere in Delaware County.

"Many times, he has restricted Darby officers from going to Colwyn and restricted Colwyn officers from coming into Darby. He has manipulated the department," she said.

"It makes us look like the laughing stock of the county."

The incident has refocused attention on long-standing proposal to combine Delaware County's police departments.
