In a letter to parents Sunday night, Friendswood ISD said it was adding additional police protection at its junior and high schools as well as officers at after-school events and field days, and it emphasized the need for students to come forward and report suspicious behavior. A day later, parents received notice that a junior high student had been arrested for making threats on social media. According to the district, the threats were posted weeks ago, but students reported it Monday to school officials. By 2:30 p.m., the student suspect was in custody facing felony charges, Friendswood police said. In a followup email to parents after the arrest, officials said that the renewed attention on safety following the Sante Fe school shooting is prompting students to report suspicious behavior. Four other incidents involving threats occurred in the Houston area, ABC 13 reported. "Students are using the appropriate avenues for reporting including finding a trusted adult and using the anonymous See Something, Say Something reporting system," the district said. In Sunday's email, the district said it was partnering with Friendswood Police Department and was increasing other measures for the remainder of the school year. "You will notice a heightened law enforcement presence in the community," Superintendent Thad Roher said in the letter. "I am grateful for our partnership with the City and FPD. The partnerships have been and continue to be a key component for safe operation of our schools." In addition to increased police staffing, each school has been asked to hire a safety monitor to keep an eye on entrances and hallways. The superintendent also said officials would review its security practices throughout the summer to make improvements long-term.
