Motorbike rider dies a week after NT crash

A motorcycle rider has died in hospital almost a week after he was hit by a car in Darwin.

The 34-year-old man was knocked off his bike by a car that was changing lanes in Coolalinga, in Darwin's southeast, on March 11, police say.

He was taken to the Royal Darwin Hospital in a critical condition but died on Saturday from his injuries.

Police say investigations are ongoing and they are yet to charge the driver of the car.
