Ten people were sickened at the Kansas City, Missouri, IRS building Friday morning thanks to a suspicious package that reportedly smelled like ammonia.
The Federal Protective Services, a division of the Department of Homeland Security that responds to terrorism and criminal acts against U.S. government infrastructure, opened an investigation after responding to IRS building Friday morning, Homeland Security spokeswoman Lucy Martinez said, The Associated Press reported.
The building was not evacuated and returned to normal business about two hours after the incident began.
A hazardous materials team took possession of the package, Martinez said.
About 10 people reported feeling ill, including vomiting and sweating, after the package arrived at the building, said Kansas City Fire Department spokesman James Garrett. Two of those people were taken to nearby St. Luke's Hospital, where they were in good condition, spokeswoman Laurel Gifford said.
Martinez said seven people were treated at local hospitals and added several people reported feeling ill with "watery eyes."
Garrett said the Fire Department checked the package for gasses and fumes but didn't find anything.
