Bryan Adams High School was placed on a modified lockdown Thursday after a student made threats against the school on social media, parents said.

The threat was issued Wednesday night on the Instagram account, baisdonefor, which is registered under the name Michael Morales. The post states:

BA is done for, I am tired of this bumm ass school, and Mr. Bott’s stupid rules. Tomorrow before spring break, 9:30 am i am going to make sure I and this school goes out in style, spread the word because i dont want to hurt nobody😉 just want to get rid of this school once and for all.

In a modified lockdown, all exterior doors are locked, outside activities are canceled and no one enters or leaves the campus, according to campus emergency procedure.

It is not clear how long the school was locked down. The spokeswoman for Dallas ISD did not immediately return a request for comment.

A parent, Alejandra Fatima, said on Facebook that she received a call Thursday morning informing parents about the threat. The call said that authorities were investigating and extra security officials would be at the  school.

Another threat was issued once school started, prompting the lockdown, she said.
