One East Bay elementary school is planning to have extra security on hand Monday after a woman attacked a 9-year-old child on campus with a hammer.
The incident happened Friday at Lafayette Elementary School in Oakland.
Police said the attacker is the mother of another child at that same school.
According to a district spokesperson, the victim was beaten during recess. When the girl's teacher noticed that she did not return to class, they immediately called a security guard and searched for her.
The guard found the 9-year old leaving the bathroom with the suspected attacker--a woman who has a daughter at the same school.
Police said crews rushed the girl to the hospital for non-life-threatening injuries.
The woman was arrested at the scene, and the district spokesperson said it may have started with a family feud off campus.
On Monday, Oakland police plans to offer the extra security.
