Two Carcoola men have found and captured one of the three adolescent Tasmanian devils that escaped from Peel Zoo on Tuesday.
Robbie Haddow and Johhny Feeley were driving home from a friend's house in Rockingham in the early hours of this morning when they spotted Scratchy, initially mistaking him for a small wild pig.
The men chased the animal through the bush, eventually cornering him in a pool of water and capturing him by grabbing him by the tail.
The pair wrapped the animal in a towel, took him back to their home and locked him in the bathroom.
They then returned to the bush in a bid to find the other two devils.
On their return to the house, they noticed Scratchy had scratched a hole in a plasterboard wall in the bathroom.
Narelle MacPherson, of the Peel Zoo, said she was thrilled one of the devils had been captured and returned.
"It gives us hope that the other two missing devils will eventually be located and returned to us," she said.
Ms MacPherson said she feared the other two animals, Itchy and Genghis, might be hit by a car or attacked by dogs, but otherwise they would survive well in the WA bush.
The three devils escaped from Peel Zoo early Tuesday morning after a big eucalyptus tree crashed into an enclosure, which housed seven of the iconic and endangered Australian animals.
The zoo - a privately-owned, self-funded, family business near Pinjarra - has since repaired the enclosure and set traps for the missing animals.
Anyone who spots the other two devils is asked to contact the zoo on 0400 788 289.
A reward is offered for information leading to the capture of the animals.
