The man said that the envelope, addressed to the Department of Workforce Development, was laced with anthrax. Milwaukee police shut down streets near the mailbox and investigated the package, which turned out to be a hoax, FOX 6 News reports.
The incident occurred at the corner of Knapp St. and Astor and forced the closure of the two streets from 5:30 p.m. to 8:30 p.m. No businesses were closed and no evacuations took place during the incident.
The man, who has not yet been named or charged, recorded a video of himself mailing the letter with a woman by his side. He spoke nonsense during the recording, mailed the letter and sent an email to multiple news outlets in Milwaukee stating that a letter laced with anthrax could be located at East Knapp St. The emails contained a link to the video, according to Fox 6 News.
The person who allegedly made the threat used to work at Accurate Metal Products, where he used computers to draw up designs. After getting the job in February, he was fired in early April following a conflict that took place between the man and a co-worker. One video showed the man making threats against his former employee. He was arrested after the incident on Saturday evening.
