Authorities say a suspicious package that sickened several people at an IRS building in downtown Kansas City, Missouri, smelled like ammonia.

Local officials say about 10 people reported feeling sick after the package was delivered to the building Friday.

Department of Homeland Security spokeswoman Lucy Martinez says seven people were treated at local hospitals. She says several people reported feeling ill with “watery eyes.” Some people reported vomiting and nausea.

Martinez says the envelope involved smelled like ammonia, but no other details were released about the envelope’s contents or where it may have originated.

The investigation has been taken over by the U.S. Treasury Inspector General for Tax Administration. The Federal Protective Service, a division of Homeland Security, also is involved.

The building wasn’t evacuated and business returned to normal about two hours after the incident began.

Two of the 10 people who complained of nausea and vomiting were taken to a hospital and were in good condition. The building was not evacuated and returned to normal business two hours after the incident began.

A fire official says about 10 people were sickened by a suspicious package in the mailroom of a sprawling IRS building in downtown Kansas City, Missouri.

The building was not evacuated and has returned to business.

Garrett says the investigation has been turned over to the IRS and other federal authorities.
