A woman has suffered “serious injuries” in Alaska when a bear attacked her near her driveway while she was out on her early morning jog, officials said.

The incident occurred early Tuesday morning when the Kenai Police Department in Alaska received a call at 6:58 a.m. informing them that there had been a bear attack near the intersection of Chinook Drive in Kenai, the Alaska Department of Public Safety said in their statement on Tuesday.

“[An] investigation revealed a 36-year-old female departed her residence at 5:45 a.m. to go jogging and was near her driveway when the initial attack occurred,” police said.

A neighbor eventually came outside and located the unnamed victim before alerting authorities to the incident.

The jogger was taken by helicopter to an Anchorage area hospital where she was treated for “serious injuries,” according to the Alaska Department of Public Safety, though no details were given about what injuries she sustained or what condition she was in following her initial medical evaluation and treatment.

“Alaska Wildlife Troopers, Kenai Police Department, and Alaska Department of Fish and Game personnel searched the area on foot and with a drone looking for the bear,” officials said. “The bear has not been located. Patrols of the area will continue, and the public is advised to remain vigilant while outdoors.”

The Kenai National Wildlife Refuge nearby contains almost 2 million acres of land along with an estimated 2,183 different animal species living there, according to the Kenai National Wildlife Refuge.

The investigation into the attack is currently ongoing.
