The sow was euthanized Saturday, according to officials.
The woman told officials she was walking home from work around 11:40 p.m. when she encountered an adult bear on the street who charged at her.
"As the victim turned to try to escape, the bear knocked her down from behind, scratching her back and ripping her shirt," Parks and Wildlife said.
The woman suffered three long scratches down her back, but was not seriously injured and did not seek medical attention. The woman also sustained cuts to her hands and legs when she fell.
Minutes later, another person was also chased by a bear on the same block just south of downtown Manitou Springs. The person was able to get away by running around a parked vehicle.
CPW wildlife manager Cody Wigner said the woman who was attacked is “very lucky” she wasn’t seriously hurt.
The bear believed to have attacked the woman was caught and humanely euthanized by wildlife officers working with federal agents.
“We believe this is the sow that aggressively attacked one woman in Manitou Springs and then chased another on Thursday night,” Wigner told FOX31.
The sow’s cubs were taken to a rehabilitation facility where they will be taught to avoid human contact before being released next winter.
“This is why we say ‘garbage kills bears’ and urge everyone to secure their trash cans,” Wigner said. “This is bear country. We need to keep them wild and not let them become trash bears.”
It was the second bear attack in Colorado in 24 hours. A large bear in Aspen broke into a home and took a swipe at a homeowner on Wednesday.
That 400-pound animal had a history of foraging through trash, officials said.
