Driver mows down 17 roos in Brisbane

A driver has deliberately run down and killed 17 kangaroos on Brisbane's outskirts.

The RSPCA is appalled by the incident that has left a 100-metre stretch of road at Wacol littered with kangaroo carcasses.

The animals were discovered on Monday morning, between the women's and men's prisons.

RSPCA spokesman Michael Beatty said many of the roos were young.

"One of them we had to euthanase, 16 of them were dead," he told AAP on Monday.

"They've definitely been deliberately run over. You can quite clearly see the tyre tracks where they've gone off the road to hit them."

The roos were found on Grindle Road, near the prisons.

Mr Beatty has appealed for any witnesses to come forward.
