SALEM — An upset man brought a pressure cooker he claimed was a bomb into the state Teacher Standards and Practices Commission office on Wednesday and informed employees he had tried to blow up their sign because it was misspelled, a state official said.

The man plunked down a pressure cooker with wires sticking out of it and said the “bomb” didn’t work, commission Executive Director Vickie Chamberlain told The Statesman Journal.

The sign in question spells out the agency’s name and sits at the end of its parking lot. One side is missing the letter “d” in the word “and” so it reads: “Teacher Standards an Practices Commission.”

The man also complained that the instructions he downloaded to make his pressure cooker device contained misspellings, Chamberlain said.

People come to the commission office to fill out applications for teacher’s licenses.

Chamberlain motioned to an employee to call police and asked the man to leave. He left, taking his pressure cooker with him.

Police arrested Leonard Burdek, 50, of Salem, a short time later for investigation of disorderly conduct, Lt. Dave Okada said.

“It looks like he was just trying to get attention,” the police spokesman said.

The pressure cooker was not a bomb, Okada added.
