Temple police arrested a 14-year-old girl Friday after she reportedly attacked her grandparents during a dispute over a cell phone.

In a report cited by our news partner, KWTX, police noted the girl allegedly struck her 76-year-old grandmother in the head multiple times with her fist. The teen now faces a charge of injury to elderly-family violence. She was placed in the custody of the Bell County Juvenile Detention Center in Killeen.

The attack allegedly happened in the 2300 block of Ridgeway Drive when the girl's grandparents tried to take her cell phone away. The girl's 71-year-old grandfather told police he knows the girl wasn't trying to hurt him, but the police report describes visible injuries to both grandparents' forearms.
