The stabbings were reported at 10:18 p.m. at a home in the 400 block of Willie Stargell Avenue, Alameda police Sgt. Jeff Emmitt said. The victims were three females and one male.
A female suspect was taken into custody at the home, Emmitt said.
Some of the victims were taken to hospitals for treatment, but none of the wounds were considered life-threatening, he said.
Emmitt said it appears the family was gathered at the home when an argument began. At some point during the argument the suspect used either a kitchen or pocketknife to stab the four others, he said.
The case remains under investigation.
