Several Chase banks in Detroit and Oklahoma were evacuated today after receiving threatening letters containing white powder, the Detroit Post reports. The letters "basically indicated that the person who opened the letter was going to die" because of "an action the bank may have taken," an FBI spokesman said. Medics checked out bank workers but officials said the powder did not seem dangerous.
Seventeen people were quarantined at one Denver bank, where a Hazmat crew identified the powder as "negative for biological, organic or radiological material," a fire department release stated. Police in Norman, Okla. called the letters sent there a hoax, The Norman Transcript reports. A worker at one Chase location was treated for a rash, but officials told Reuters that the powder may not have caused it.
