Authorities with the Clay County Sheriff's Office and North Kansas City Police Department are investigating what they believe to be a "swatting" call at an area high school Monday morning. Sarah Boyd, the spokesperson for the Clay County Sheriff's Office, said someone called the NKCPD non-emergency phone number around 11:50 a.m. and reported a shooting inside North Kansas City High School.The caller, who had an accent that was difficult to understand, Boyd said, told authorities that multiple people had been shot in a specific room of the high school.No other 911 calls came in to corroborate the report.Boyd said officers and deputies quickly responded to the school and determined there was no threat, and that the call was likely a "swatting" incident.Swatting is where an individual makes a prank call to law enforcement with the hope of authorities dispatching a large number of officers to a specific location. Boyd said the school was placed on lock-and-teach for a few minutes as authorities investigated. Authorities continue to work to determine the source of the false threat. In addition, police in Sedalia, Missouri, said a similar call was made regarding Smith Cotton Junior High School. The shooting call was unfounded. "There has been a national trend recently where prank callers have called schools around the Midwest, and even Missouri, reporting acts of violence in local schools," police said in a news release on Facebook."The Sedalia Police Department will investigate this report and work to determine who is responsible for making the call." Knob Noster Police also said they received a similar call regarding Knob Noster High School in Johnson County, Missouri.
