Gisborne police are investigating stock killings in which one of the animals was shot with a crossbow.
Manutuke police constable Tim Winchester said the dead stock were found on the side of Parikanapa Road, about 30 minutes from Gisborne, last Thursday.
"A farmer found the remains, and removed a crossbow bolt from the carcass of a sheep," Constable Winchester said.
"He found other remains at the scene, indicating two other sheep had also been killed."
Constable Winchester said the crossbow bolt came as part of a set. The bolt recovered was not readily available in Gisborne.
