Authorities say an Allendale police officer who was seriously injured by a suspected drunk driver on Oct. 6 has been released from the hospital.

Mark Dunn was assisting another officer during a traffic stop on the shoulder of Route 17 when an SUV veered into his patrol car.

It caused a four-vehicle chain reaction that left him with a broken pelvis, femur and shattered hand.

The driver of the SUV is accused of driving while intoxicated and speeding prior to the crash.
