A Santa Rosa police officer and a juvenile suspect were injured in a struggle Tuesday afternoon, police said.
Officers responded at 1 p.m. to a disturbance between the suspect and her neighbor in the 1400 block of Hogrefe Way.
The first officer there encountered the neighbor and the girl who allegedly was physically and verbally combative with the officer.
Police said the officer used a departmental approved takedown on the girl to detain her. She continued to resist and the officer handcuffed her.
Police said the officer suffered abrasions to a hand and injured a finger. He was treated at a hospital and released.
Police said the girl suffered abrasions to a hand and her face and received care at a hospital before being taken to juvenile hall.
The girl allegedly had brandished a box cutter-type knife and threatened to kill her neighbor.
Police said the girl was arrested on suspicion of criminal threats, battery on an officer and brandishing a weapon.
