Rumors among students on social media have officials at Eden Prairie High School taking extra precautions.
KARE 11 says a report of a gun being brought school on Wednesday prompted a stepped-up police presence Thursday. No gun was found, but the threat was followed by suspicious messages online.
School officials say a "high volume of social media statements" indicates tension running high between students and extra security was added to ensure everyone's safety.
Principal Conn McCartan tells the Star Tribune that two extra police officers will be on school grounds in addition to the two regularly staffed school resource officers.
A letter was sent to parents notifying them of the situation.
