A 12-year-old from Stamford, Conn., was arrested on Tuesday after police say she continually bullied, taunted and harassed another student while at school.
Police said the victim's parents contacted the department to report the bullying on Sept. 20. Both students attend a private middle school.
The bullying intensified while police and school administrators investigated, pushing the victim to make suicidal comments, according to police.
Police said the pre-teen was charged with disorderly conduct and was released to the custody of her parents.
"This behavior will not be tolerated by Stamford Police Department," said Capt. Richard Conklin and Lt. Diedrich Hohn, in a release.
"If it is brought to our attention we will vigorously investigate the allegations and make arrests when appropriate. We investigate all claims of bullying and this type of behavior will not be condoned in a learning environment."
