COLORADO SPRINGS, Colo. -

One Colorado Springs post office is still closed after police found two men with meth-making materials in the lobby Saturday night.

Police said Michael Tessler, 28 and Garin Shaw, 21 were found at about 10:30 p.m. Saturday sitting in the foyer at the post office on East Uintah near North Circle Drive.

Police said Tessler and Shaw were both decontaminated and arrested.

According to Ron Perry, spokesperson for the United States Postal Service, a Hazmat team was called out to test the air to make sure the foyer was safe.

"The air was deemed to be clean," said Perry. "But they did some swabs that are being tested right now."

Perry said the additional tests will confirm whether or not the air is safe for the public to breathe.

A USPS spokesperson originally told KRDO NewsChannel 13 on Monday that the post office will re-open Tuesday at 8 a.m, but now says more cleaning needs to be done.

Perry says the post office will not open until Friday at the earliest.

The USPS decided it should hire a professional clean-up company and then have an additional test done afterwards.

The retail lobby will be closed, so customers who need to perform revenue transactions such as buying stamps or mailing packages will need to visit another post office location.

While the USPS awaits the test results, the retail lobby will be closed for revenue transactions, which includes buying stamps and mailing packages.

A mobile unit is set up in the parking lot to help customers with non-revenue transactions, which includes picking up packages.
