An accident that is causing ongoing morning delays around the Edsall Road exit on I-395 is the result of a police chase, officials said Tuesday.

At about 4 a.m., a Fairfax County police officer tried to flag down a car on I-95 North near Fairfax County Parkway. Instead of pulling over, the driver fled.

The officer, soon backed up by additional cruisers, pursued the car.

The chase ended with a collision that resulted in the civilian car being pinned against the guardrail by one of the police cruisers near the Edsall Road exit, police said.

The driver and one officer suffered minor injuries. The right lane, right shoulder and exit 2A on I-395 North are blocked.

The pursuit and the crash are under investigation.
