Three people were stabbed, one fatally, in a group of attacks in the Berkeley Hills on Saturday afternoon, police said.
The dead victim, a woman, was found in the 900 block of Overlook Road, police said.
A person who fled the scene was later taken into custody at Gilman Street and Ninth Street after a chase by police.
Police said they received numerous calls at about 12:30 p.m. reporting a person with a knife in the 900 block of Overlook Road, and another incident on the 1000 block of Overlook Road. One caller said a person with a knife was chasing someone down the street, police said.
Multiple neighbors told NBC Bay Area they heard screaming and yelling, followed by calls for help as it appeared a man was being chased by another man down the street.
Police say they arrived to find one woman had been stabbed to death the 900 block of Overlook Road location.
They believe the suspect then chased a man who lived in that home with her down Overlook Road. Police say the suspect left that man with injuries on his hands and also stabbed a female neighbor who was a bystander.
Berkeley Police say that female bystander had to be hospitalized due to her injuries and at last check she is said to be in stable condition.
Officer Jessica Perry, Public Information Officer for Berkeley Police, explained the woman who was killed was in a relationship with a man who was injured and that they both knew the suspect. However, Berkeley Police declined to comment on how the suspect knew these two victims.

As officers were on the way to the scene, they were advised that the suspect fled in a vehicle. Officers spotted the car traveling away from the scene and pursued it until a collision occurred, and the suspect was arrested, police said.
That crash occurred at 9th and Gilman Street, around 3 miles away from the initial attacks. Police said that the suspect fled in a stolen vehicle.
"I just heard a man running down the street yelling , 'help, help, help!'" recalled one neighbor.
This neighbor, who did not want to be identified for fear of her safety, explained that she was devastated to learn her friend and neighbor had been killed in this attack.
The neighbor said the woman who had been killed had just gotten engaged days ago and had dropped by earlier to share the good news.
"She was a very helping kind of person and she really was a wonderful person, I was privileged to know her as a neighbor," this neighbor said of her friend.
Berkeley Police have not released the names of the people involved yet or what they believe the motive was for these attacks.
