PHILADELPHIA — Authorities say charges have been filed against a sport utility vehicle driver accused of dragging a Philadelphia police officer about five blocks after a traffic stop.

Police said officers stopped the vehicle at about 9:15 p.m. Tuesday in west Philadelphia for traffic violations when one officer noticed a bulge on the right side of the driver’s waistband. Police said he shut off the vehicle as ordered but then started it again and took off, causing another officer to fall into the vehicle.

The driver fled at high speed with the officer still inside the SUV, and a struggle between the officer and the driver ensued, police said. Police said the SUV hit several parked cars and finally came to rest.
