Arkansas man arrested for anthrax hoax

A northwest Arkansas man has been arrested for allegedly mailing threatening letters containing a nontoxic, white powder to the employees of a Christian greeting card company and to multiple other locations.  
According to court documents released Tuesday, Philip Hanson allegedly sent the letters to DaySpring, where he used to work, and to other people and businesses nearby. One of the letters told the reader that he should to have a will made out and increase his security at home, the Associated Press reports.
One of the mailings prompted the evacuation of the Northside Elementary School last week in Siloam Springs when a letter containing white powder was delivered to a teacher's mailbox. Nobody was injured by the white powder, which authorities said was not dangerous. Some of the substance was identified as baking soda.
The Federal Bureau of Investigation said that Hanson was charged with mailing threatening communications. More than 40 suspicious letters were sent to individuals and nearby businesses, with 30 of the letters containing a white, powdery substance. Kent Raymick, the school's assistant superintendent, said that the teacher who received the letter is related to an official at DaySpring, the AP reports.
A hazardous materials crew responded to the school and tested the substance last week upon discovering the powder. Officials determined that the substance was harmless and everyone was allowed back in the school building shortly after noon.
During an initial appearance in federal court in Fayetteville on Tuesday, Hanson waived his right to a detention hearing.
