UNIVERSITY PARK (CBSDFW.COM) – Threats at Highland Park High School have included notes, bullets and now an email tip.

Police say the anonymous email came through Crime Stoppers around 8:30 Monday morning. It wasn’t very detailed. Names, dates and times were left out.

“It’s someone who had overheard some people talking about a bomb at the high school and so they reported it to Crime Stoppers,” said Captain Leon Holman of the University Park Police Department.

10 officers searched the building. No threats were found. No classes were cancelled.

“It simply did not strike us as a credible threat,” said Dr. Dawson Orr, Highland Park ISD Superintendent.

“So, we’ve continued with kids taking tests, working on projects. You know, going about the business of learning,” he said.

Since January, there have been: four notes in one boy’s bathroom, .22 caliber bullets in another boy’s bathroom, a note at the top of a stairwell and now the Crime Stoppers tip.

“We’re all hoping this will be resolved. It’s very disconcerting. It’s upsetting. It causes needless anxiety, loss of resources,” said Dr. Orr.

Crime Stoppers is offering a $10,000 reward for information that will lead to the arrest and indictment of a suspect or suspects.
