Five young swans have been left injured after reportedly being shot at by someone using a catapult and ball bearing.
The attack on the cygnets was believed to have happened between 19:00 BST on Saturday and 14:00 on Sunday on the Chesterfield Canal, around Browns Lock, in Rotherham, according to South Yorkshire Police.
They were taken to a rescue centre for treatment, where two remained in a serious condition and three others were recovering well, a force spokesperson said.
Officers urged anyone with information about what happened, or who had seen anyone acting suspiciously in the area at the time, to get in touch.
