AVON, Colorado - A substance on the side of an Avon man's car made him sick when he stepped out check his mail, and when Avon police showed up to investigate it made them sick, too.
That's when police and fire departments closed the Avon Post Office and a two-block area around it.
The call came about 1:15 p.m. Tuesday when an Avon man drove to the post office in a late model maroon Honda Accord sedan. When he stepped out of his car, he became nauseous and his heart started beating fast, said Avon Police Chief Bob Ticer.
He made his way into the post office, and that's about the time emergency personnel were called.
The first two Avon police officers who arrived on the scene also got sick, showing the same symptoms, Ticer said.
The area was closed off and people were kept inside the post office until it was safe to take them out the back door, Ticer said.
The two block area was closed off. It remained closed for the duration of the incident.
Authorities were working to determine what the substance was.
