Two notes threatening actions similar to the infamous shootings at Columbine High School were found written on a bathroom stall in Gladfelter Hall, Fox 29 reported Thursday.

The station reported images of the messages which read: “April 20, 2013, I’ll bring honor to Eric Harris and Dylan Klebold,” and on the same date, “you will all learn the meaning of suffering.”

According to the report, the university first found out about the messages in March. No alert has been released through the TU Alert system.

Fox reported a statement from the university officials which read: “The safety of our students is a top priority. Temple Police have been conducting an investigation into the graffiti message, security has been enhanced on our campus.”

April 20 is the 14th anniversary of the Columbine massacre in Colorado which left 12 dead and 21 injured.
