FBI Nabs Man Suspected of Poisoning Produce at Grocery Store

— -- The FBI has arrested a Michigan man for allegedly spraying a poisonous mixture of chemicals on food at three grocery stores in Ann Arbor, Michigan.

The FBI and Michigan Health Department are now looking at whether anyone was seriously ill from the low-scale chemical attack to contaminate food.

Authorities believe the unidentified suspect targeted at least three grocery stores in the past two weeks: Whole Foods, Meijer and Plum Market. Law enforcement officials are also now trying to determine whether he victimized other stores with his toxic mixture of hand-cleaner, water and Tomcat mice poison.

"What if he's been doing this for weeks, or months, or even years, and just suddenly someone saw him?” one concerned citizen said. “Makes you think about everything you buy all the time."

As of now there is no indication of terrorism, sources said.

The FBI had released photos of the suspect Sunday, seeking the public’s help in identifying him.

“The FBI and Ann Arbor Police want to thank the media for bringing attention to this matter, and the public for their assistance,” the FBI said in a statement Tuesday.
