UPDATE:

LINDEN -- Linden High School was locked down for most of the day Tuesday after someone behind an anonymous Instagram account threatened to shoot up the school.

The threat came from an account named "lhslasthours" and began around 8 a.m. with a photo of a rifle laid over a car's steering wheel with the caption "11:36 a.m."

The subsequent posts continued with no photos, but captions that read "Shooting anyone who gets in my way of getting up to [redacted]" and "Do all your little drills I'm already in the building."

The two most recent posts say, "2nd floor goes first" and then, finally, "Too many cops. Got till 12 to leave the building I'm blowing it up real simple. Go"

In one other post that has since been deleted, the poster said, "Everyone makes shooting threats towards Linden High school and it never happens. I will make your wish come true. The freshman and sophomores the Juniors the seniors. I hate Linden I wanna see you all suffer. My name is [redacted] and I will shoot up your school at 11:36AM"

No one with the listed name appears on any other social media website or comes up in a Google search. However, NJ Advance Media has redacted all names from the posts in order to protect anyone with those names.

Police Chief Jonathan Parham briefed the press as the day progressed, until finally at 1 p.m. the lockdown was lifted. Students were then dismissed, as the school could not accommodate all students for lunch once the lockdown was lifted.

Students still were allowed to stay for lunch if they wanted to and after school programs are proceeding, Parham said. He declined to talk more about the investigation or say if anyone was in custody.

Robin Carter, whose daughter is a freshman at the high school, said her daughter was texting her, telling her students inside were distraught.

"They're scared, they're crying," she said.

Students said they were locked down in their classrooms for hours and were able to look up the threat on social media.

"Everybody was following it on their phones," said Sean Morgan, a freshman, who was stuck in his Mandarin class. "Some people cried, they were sad."

Students saw the photo of the gun across the steering wheel, but after studying the picture, many decided it was fake.

"If you look at it, it had a temperature of 73 degrees," said student Cory Cobe, referring to the temperature registered on the dashboard of the car in the photo.

He also said the time on the dashboard did not match up with the real time.

School staff told students to put their phones away and some students had their phones taken away, Morgan said.

Students said this was the third threat he had heard about this school year.

"It's getting kind of aggravating lately," Cobe said.
