Police say a threat was made against Trinity High School on social media.

The threat was made before Jeff Brohm said he would stay at Purdue instead of coaching U of L football.

The latest:'It was never a threat.' Man behind Trinity tweets arrested, lawyer says

Trinity High School canceled classes Thursday because of "a threat against the school due to Jeff Brohm deciding to remain at Purdue."

School officials were notified of the alleged threat by police, the school said in an announcement Wednesday. Offices will be closed and classes will be conducted online Thursday.

St. Matthews Police Chief Barry Wilkerson told the Courier Journal late Wednesday night that the threats were made on Twitter and referenced burning down the school. He said Trinity made the decision to close.

Brohm graduated from Trinity in 1989 and played quarterback before attending the University of Louisville. His brothers, Brian and Greg, also attended the Catholic high school. His father, Oscar, coached football at Trinity.

He announced Wednesday night that he would remain the head coach at Purdue, declining an offer from Louisville to become its next coach.

On Thursday morning, authorities publicly identified the Twitter user as "Proud Clarion" but did not know the person behind the account. The FBI and St. Matthews Police asked the user to come forward.

The Courier Journal's attempts to reach the Twitter user have been unsuccessful. The account went private late Wednesday.

In the tweets, which were posted before noon Wednesday, Proud Clarion @RTPB07wrote, "If Jeff Brohm doesn't come, we burn down Trinity," and "If you see a man running down frankfort with a gas can and wild look in his eye, its me".

Another tweet read: "*me, out front of Trinity, holding a single match and addressing Jeff Brohm directly* I'LL F------ DO IT".

Tony Cobaugh, assistant chief of St. Matthews Police, said Thursday that charges of terroristic threatening are possible.

"We live in a society now and in a world today where shame on you if these things lightly," Cobaugh said. "It doesn't matter if it was satirical, and it doesn't matter if it's involving a favorite son and alum of the school who is now a D1 football coach."

Some took to Twitter to label the tweets as sarcasm.

Mark Ennis, radio host on 93.9 FM in Louisville, the ESPN affiliate, said, "the person accused of tweeting the threat is easily (one of) the funniest Louisville fans I know and his tweets were so obviously over the top that no sane person would take them as an actual threat. The guy bought a promoted tweet once to mock Bama fans. This is ridiculous."

"The same guy who allegedly threatened Trinity said Louisville should pick between Neal Brown or the bubonic plague for its new coach. This is an absurd overreaction. Shame on all of you. He was *mocking* overreaction, not reacting," Ennis wrote in another tweet.

The FBI and Louisville Metro Police are assisting with the investigation.

“We just feel like we need to use every resource we can," Wilkerson said.

The department also increased patrols in the area of the school starting Wednesday night.

Trinity Principal Dan Zoeller alerted staff of the threat late Wednesday and said he would provide more information as it became available. He did not respond to a Courier Journal email seeking additional comment sent Wednesday night.
