Holt Lutheran School reportedly closed Monday after receiving a bomb threat. According to lsj.com, the threats came VIA e-mail last week on multiple occasions while the school was on Spring Break. The article says that "nonspecific" threats were sent to school officials, meaning no direct threats towards students or the school's buildings were given. School officials plan to resume classes Tuesday as authorities say there is no imminent danger. The FBI is investigating the case along with Ingham County Sheriff's officials. According to investigators, the threats came from out-of-state. The closure of the school today has allowed deputies to sweep the building for explosive devices.
