UPDATE: Lafayette High School in Saint Joseph has been released from lockdown.

Officials released the school from lockdown around 2:30 p.m.

School officials say everyone in the building was directed to shelter in place beginning at about 1 pm because of the threat of a weapon inside.  Police say the threat was made on social media and in text messages.

“We had received information that was possibly making threats,” said Capt. Jeff Wilson with the St. Joseph Police Department. “It was enough information to warrant a lockdown, at that time a lockdown did take place.”

Wilson said police searched the building and continued to investigate outside sources of information on the individual’s whereabouts.

A man in his late teens was detained by police for questioning.

“It doesn’t appear at this time that he was in the building,” Wilson said.

Police are investigating the threats.
