FAIRFIELD - The Essex County Prosecutor's Office says an alleged drunken driver tried to run down a police officer today and wound up being shot.

The incident happened on Route 46 between Plymouth Street and Clinton Road in Fairfield.

Two police vehicles were towed from the scene hours after the incident, and News 12 has learned that one of them was hit by a blue pickup truck.

According to the prosecutor's office, a concerned driver called 911 about the blue Ford truck, saying that the driver appeared to be drunk.

As Fairfield officers were investigating the scene, the pickup allegedly tried to drive off and crashed into the marked police car. The truck drove over a median and headed toward an officer. 

The officer subsequently fired and hit the suspect in the head.

The 46-year-old Morris County resident was airlifted to St Joseph's Hospital where he was listed in critical but stable condition.

While the suspect has been arrested by Fairfield police, his name won't be released until tomorrow when charges are filed.

Route 46, which was closed earlier due to the accident, has reopened.
