There will be heightened security at Port Arthur's Memorial High School on Monday morning, after clown-related threats of a shooting circulated online.

According to Port Arthur I.S.D.'s Facebook page, the district was notified of the threats by the city's police department. Officials say parents began calling 911 about the threats Sunday evening, and reassured the public that both P.A.I.S.D. and police are aware of the situation.

Port Arthur I.S.D.'s Superintendent, Dr. Mark Porterie, also took to the district's Facebook page to reassure parents that it is safe to send children to school. In his message, Dr. Porterie says there will be a heightened security presence to ensure the safety of the campus.

There are a number of schools named "Memorial" nationwide, and while the threats did not mention Port Arthur specifically, district officials say all threats are taken seriously.

This particular threat has been circulating across several states, and seven teens have been arrested so far.

In his message to parents, Dr. Porterie also said, "...those that are found to have committed these acts will be punished to the fullest extend of the law."
