ATHENS, Ohio (AP) -- Officials say the white powder that led to an evacuation of a building at Ohio University last week was toothpaste used to seal an envelope.
The University said the envelope contained an application and background materials from a West Virginia prison inmate.
Authorities interviewed the person who mailed the package and determined that toothpaste had been used to seal the envelope.
The toothpaste had dried and flaked into a powder.
The discovery of the white powder Thursday led to the evacuation of employees from the OU legal affairs office and a bank branch in the same building. The FBI and a weapons of mass destruction team from Rickenbacker Air Force Base in Columbus were called to investigate.
Officials said the employee who reported the white powder acted appropriately.
According to an alert on Ohio University's website, the incident happened just before 11:20 Thursday morning.
The alert says that as a precaution, OUPD evacuated the Legal Affairs and People's Bank sections of the West Union Street Office Center and took other steps to isolate the potentially affected area.
OUPD says they do not believe other areas of the WUSOC building are affected at this time. They are working with authorities for assistance in identifying the powder and sender of the letter.
According to the alert, at this time, it is believed that this is an isolated incident and no further action is needed by OU faculty, staff and students.
No other details are being released at this time.
