Police investigate suspicious package at N.C. immigration office

Police are investigating a suspicious package found in the mail room of Citizenship and Immigration Services, in Research Triangle Park near Durham, N.C., according to an ABC News report.

Three mailroom employees complained of having nausea and itchy eyes, according to the police. A manager noticed and notified police. Police said the workers were decontaminated before going to the hospital. The package arrived Monday and had an oily sheen on the outside of it, according to police.

The building was evacuated shortly after 10 a.m., and was decontaminated by Hazmat teams, police told ABC News. Employees were allowed to re-enter the building at 1 p.m.

“All those tests at this point have been negative testing, but they are preliminary tests,” Durham Police Department Captain D.C. Allen told ABCLocal.go.com. “They have recovered the package and it will be taken to the Public Health lab in Raleigh for some further testing.”

Officials said they are looking at the possibility of a link between the immigration office scare and a Monday incident which occurred at the state capitol building.

The capitol was evacuated Monday evening when a staffer in Governor Beverly Perdue's office opened a letter that contained white powder. The powder tested negative for hazardous materials, according to preliminary results from the N.C. Division of Public Health.

The capitol was closed to the public Tuesday as a precaution and a criminal investigation has been opened, according to state police.
