WILKINSBURG, Pa. – A 16-year-old Pennsylvania girl was arrested today after she allegedly poured gasoline on a school security officer and attempted to light him on fire.

Wilkinsburg School District officials evacuated Wilkinsburg High School, as well as its middle school, after a female student allegedly attacked at guard at the high school with a container filled with gasoline around 9:30 a.m., CBS Pittsburgh reports.

It’s unclear what type of container the gasoline was in, with some reports detailing a “2-liter” filled with gas and others describing a “soda can.”

“My daughter called me and I guess she was on the third floor and she started smelling the fumes,” parent Shadon Sewell said. “She said they wasn’t releasing them, they’re not releasing them and she was getting dizzy and everything so I came down here.”

Wilkinsburg High guard Brandon Murry told WTAE the teen threw milk on him last Friday, and returned to school Monday with gasoline in the bottle. When he wouldn’t allow the girl to enter school with the container, she sprayed it in his face and pulled out a grill lighter, but was restrained by another guard before she could set him ablaze, Murry said.

The incident occurred at the front entrance of the school – near its metal detectors – as students were checking in for the day. District officials refused to release the names of anyone involved. Students were ushered to a nearby community center, Hosanna House, before they were eventually sent home for the day. Students were inside the school with the gas fumes for about 45 minutes before it was evacuated, according to media reports.

“Parents have been notified via alert now which is our mass response system. We’re going to keep them appraised as much as we can,” acting superintendent Joseph Petrella said.

School officials told CBS Pittsburgh the student was arrested, but did not disclose any pending charges. Murry was not injured in the attack and remained at the school throughout the ordeal after changing into sweats.

School board president Ed Donovan told the Pittsburgh Post-Gazette the girl involved was suspended from the school Friday because of the milk incident, but officials released no other details about the teen or her issue with the guard.

“I cannot comment on student matters,” Petrella said.

Sewell said she’s upset because she had to learn about the problem from her daughter, who called before school officials notified parents. She has two daughters – a freshman and a junior – attending Wilkinsburg High School, she said.

“It’s terrifying. This school is just a mess. I’m really over it,” Sewell said.

Other parents didn’t seem as concerned.

“They got everyone out safe and into another building,” Stephanie Jones, whose son is a junior, told the Post-Gazette.
