Someone had called 911 from a blocked number claiming to have a pipe bomb. The caller said he was going to kill everyone inside the mosque during the November 2018 incident. The bomb threat turned out to be a “swatting call” — a dangerous form of harassment intended to get police SWAT units to respond to a target’s location.
