An Australian tourist shot directly in the eye with a paintball gun will remain in hospital overnight while the pressure in his eye stabilises.
The man's right eye was seriously injured when he was shot from a moving van while cycling near Hanmer Springs last night.
Police said the cyclist was about 4km out of town on State Highway 7, on his way to Nelson, when he noticed a vehicle approaching about 6.10pm.
"He was hit in the right eye by what he thought was a bird. He slowed, lost balance and fell of his bike.''
The tourist looked back and saw what appeared to be a white or light-coloured van driving away from him.
