After a 12-year-old Longmont girl punched her mother in a second incident, the mom had the girl arrested to "send a message," police said.
Police were called Monday night on a reported family disturbance in the 300 block of 21st Avenue.
Officers said they found the mother and daughter sitting on separate couches on opposites sides of the living room.
A son told police that this sister had hit his mother in the face and body several times and pushed her around, according to a police report.
Police did not release the names of the mother and daughter, because state law generally prohibits law enforcement from identifying juvenile suspects.
The mother did not speak English well, so her son often translated for officers.
The son said the mother and daughter had had a stormy day since the mom went to pick the girl up that afternoon at Heritage Middle School and they had a verbal argument.
The daughter refused to get in the car, and the mother left her in a park next to school and drove home, the police report said.
Several hours later, the daughter still hadn't come home and the mother left for work.
The mother came home to find her daughter was there and she had a friend visiting.
The mother told the girl she could not have any friends over and the daughter became upset, the report said.
The mother called the friend's mom to come and pick her up.
The friend's mother arrived and spoke with the angry 12 year old about the conflict she was having with her mother, the report said.
After the friend and her mother went home, the 12 year old became very upset and confronted her mother about calling over her friend's mom, the report said.
The mom tried to walk away and go upstairs, but the daughter pushed her away from the stairs, the report said.
They went into the living room, where the daughter attacked her mother, punching her in the face, the stomach and the arm, the report said.
The son stepped in to stop the attack, police said.
The mother told police she wanted her daughter arrested because this was the second time the girl had assaulted her and "she needed to send a message," the report said.
The girl was handcuffed and arrested on suspicion of misdemeanor assault and harassment involving kicking, shoving or touching, said Longmont Police Cmdr. Jeff Satur. The girl was taken to Boulder Juvenile Detention.
