A town in western Colorado saw its second bear attack in just over a month when a bear knocked a man to the ground in his backyard Saturday night, state officials said. 

The man survived after he grabbed his gun with his free hand and fired three shots to scare off the bear, Colorado Parks and Wildlife said in a news release. 

A family member took the man to the hospital where he was treated for injuries to his arm and hand. He also suffered bruising to his chest from the bear being on top of him, officials said. 

CPW officials arrived at the man’s home in New Castle, Colorado, around 2 a.m. on Sunday morning to look for the bear. It was unclear whether any of the bullets struck the bear, but heavy rain would’ve made it difficult to spot a potential blood trail anyway, officials said. 

The local sheriff’s office deployed a drone with an infrared sensor to aid in the search, but authorities were unable to locate the bear by Sunday night, CPW said. 

The victim, who was released from the hospital Sunday morning, said he had seen the bear in his yard the two nights previous to the attack. CPW said in its statement it would continue the search Monday.

A CPW spokesperson told USA TODAY Tuesday officials did not find the bear and called off the search.

Saturday night’s incident marked the second bear attack in New Castle, a town of roughly 5,000 people, in recent months.

In August, a mother bear traveling with her cubs swiped at a woman in her yard, lacerating the woman’s arm. The woman survived and was treated at a hospital, but the mother bear and one cub were euthanized.
