UPDATE: Quarantine lifted at Beloit health clinic
BELOIT -- City of Beloit officials say 56 people were quarantined for six hours Wednesday, after a suspicious envelope was delivered to a health clinic. Three people were decontaminated, and 15 people including two first responders were taken to the hospital.
The man who delivered the envelope is believed to be a patient at the health center. We're told he dropped off the envelope like it was a bill. Investigators are still working to identify him.
Three workers who handled the letter suffered irritation to the eyes, nose and throat after coming into contact with a powder.
At least 15 people were taken to the hospital to be checked out, including two emergency responders.
Police in Beloit say they didn't want to take any chances, and implemented a full response, even if this turns out to be a hoax.
A police captain on scene says tests on the powder have come back as negative for a chemical or biological agent.
