NEW ULM - Local postal workers are not taking the bomb threats made against area post offices lightly.
New Ulm Postmaster Dave Wintheiser said his staff revisited security procedures after the New Ulm Post Office received a letter Thursday from a person, who stated an intention to detonate a bomb inside the building.
The New Ulm location was among eight post offices in this area that received such a letter on Thursday.
Wintheiser said he opened the suspicious letter personally, as he generally opens all the mail addressed to the New Ulm office. He immediately called police and the U.S. Postal Inspection Service in St. Paul.
He described his reaction as "shock, certainly fear, certainly concern not just for my own safety but for my own employees at this facility."
Reaction to the letter varied among local postal workers from concern to disbelief, Wintheiser said.
"We're not taking this lightly," Wintheiser said. "We're going to try not to leave ourselves open to any security breaches here."
A threat of this type is considered a terroristic threat, a federal offense.
The New Ulm office is going to keep its facility under tighter lock and key in wake of the threat. The threat and the investigation will not affect service at the post office, Wintheiser said.
U.S. Postal Inspector Jeff Long said facilities in Lake Crystal, Le Sueur, Le Center, North Mankato, Mankato, Sleepy Eye and New Ulm reported suspicious letters on Thursday. All eight buildings were checked and no bombs were found, he said.
"There's really not a lot we can say," Long said, citing the ongoing investigation. "Except postal employee and postal customer safety is our top priority."
