CHESTER, Pa. (WPVI) -- A 17-year-old girl has been arrested after police say she made an online threat against the Chester Upland School District, Chester Community Charter School, and Chichester High School.
The threat was posted shortly before 7 p.m. Tuesday on Instagram. The student allegedly threatened an attack against students at these schools.
The message contained a threat to "shoot up" students in the schools, and ended with "all blacks must die."
The FBI and local authorities quickly responded, arresting the girl in the 1300 block of Harshaw Street in Chester Township, where she was sleeping over at a friend's house.
Police say she admitted to writing the post.
Students at Chester High School returned to class on Wednesday after two snow days, and some were anxious after over the threat.
"People took it serious, just like I did. I felt as though it wasn't funny at all," said freshman Shaniya Dinnie.
"As a parent, I think it's ridiculous someone would do that, but I'm glad they caught the person who did it," said Rose Manual.
The teen is charged with terroristic threats, a misdemeanor, and unlawful use of a communications facility, which is a felony.
The girl is not being charged as an adult.
Parents we spoke to said they were happy that the district kept them in the loop about the situation.
