Orphaned lamb in WA police custody

Orphaned kangaroo joey Cuejo isn't the only baby animal in West Australian cop custody, with a lucky lamb now calling Mundaring police station home.

The orphaned six-day-old lamb is keeping warm in a washing basket under Senior Constable Emma McNaboe's desk after he was found abandoned on her property near York, in WA's wheatbelt, earlier this week.

Sen Const McNaboe said she brings the little lamb, named Buck, into work every day to make sure he's adequately fed.

She said Buck was relatively well behaved for a new recruit.

"If he's left on his own he starts baaing and jumps out of the basket to look for someone, but he's pretty good," Sen Const McNaboe told AAP.

"Buck's in the office at the moment and I've got a little lead set up for him outside on the grass area."

Sen Const McNaboe said she would keep Buck on her property once he was fully grown.

"Either way he'll be with us for the long run - we're not going to eat him or anything."
