MOUNT CARMEL - A 19-year-old borough woman has been charged with assaulting a policeman, breaking his glasses and smashing a chair in a holding cell early Wednesday involving incidents that began after she was found allegedly under the influence of alcohol at Seventh and Pear streets.

Amber Lynn Knopp, of 342 S. Oak St., remains incarcerated in the county prison on charges of aggravated assault, two counts of simple assault, criminal mischief, underage drinking, disorderly conduct, public drunkenness, resisting arrest and harassment.

She is accused of punching, kicking and head-butting Lt. Christopher Buhay after being taken into custody at the borough police station. During the assault, Buhay suffered a bloody nose and had his glasses, valued at $226, broken. Knopp also broke a $50 chair in half while being detained and repeatedly used obscene language toward police.

Police said they found Knopp covered in black dirt walking with no shoes on at 12:55 a.m. at Seventh and Pear streets. While police were speaking to two other individuals in the area of Seventh and Maple streets, Knopp, who was being detained in a police cruiser, started yelling and kicking in the rear of the car before being told to stop by Buhay, police reported.

After initially stopping the unruly behavior, police said Knopp started yelling again upon arriving at the police station and threw herself on the ground. As Buhay attempted to get the woman on her feet, she struck the lieutenant several times before being handcuffed by Buhay and Mount Carmel Township Officer Matthew Filarski.

Once inside the station, Knopp continued to yell and refused to walk, prompting police to carry her to a holding cell, where she began screaming, cursing, banging her head and kicking her feet before breaking the chair, police said.

Knopp was arraigned by Magisterial District Judge Hugh Jones and committed to Northumberland County Prison in Sunbury in lieu of $15,000 cash bail. She is scheduled to appear for a preliminary hearing before Jones on Wednesday.
