A bomb threat was called into MacArthur High School this morning, prompting an immediate evacuation at the same Irving, Texas, high school where freshman Ahmed Mohamed brought in a homemade clock-in-a-box on Sept. 14 that school officials deemed a “hoax bomb.”

Police spokesman James McClellan confirmed that someone called the school’s main phone at 9:45 AM from an anonymous number and said a bomb would explode in 30 minutes. According to KDFW-4 (FOX), school officials took the call seriously. Teachers and staff evacuated the school, moving all students to the football field while police swept the campus, searching each building. Officers found nothing suspicious, giving an “all clear” and students were allowed to return to class around 10:45 AM.

Police called the bomb threat a “hoax” and continue to investigate the incident, objectively to locate the individual behind the bomb threat, who, when found, could face state felony charges and receive from two to six months in jail plus a $10,000 fine.

During the threat, some parents chose to pick up their children after getting a text alert or automatic phone call about the evacuation. One mother told KDFW-4 she didn’t feel comfortable leaving her child there because she wasn’t getting enough information from the district.

MacArthur is the same high school where Ahmed Mohamed brought in his homemade clock project that did not resemble a clock but instead a possible suitcase bomb and resulted in the teen’s arrest at the time, although no charges were filed. Under the Texas Safe Schools Act of 1995 and state’s education code, Irving ISD officials acted in response to today’s bomb threat no differently than they reacted to Mohamed’s confusing-looking clock. The boy continues to espouse himself a target because of his Muslim faith, although Breitbart Texas reported that zero tolerance policies, not racism or Islamophobia, were behind his arrest.

Mohamed’s parents since unenrolled him from MacArthur High School and withdrew him from Irving ISD. The 14-year-old is believed to be overseas, invited to visit Qatar by the Qatar Foundation, which gives to educational causes. Their sister institution, the Qatar Foundation International (QFI), recently granted the Arabic Immersion Magnet School in the Houston Independent School District $75,000.
