ST. PAUL (AP) -- Officials at the College of St. Catherine were waiting Tuesday for test results on an unknown white, powdery substance found in the basements of two buildings.
The substance was discovered Monday morning in the mail room of Derham Hall, which houses the school's administrative offices, and in a basement classroom in Whitby Hall, college spokeswoman Julie Michener said. Officials closed both buildings for a few hours as a precaution but reopened them shortly after midday, except for the rooms where the powder was found.
"At this time there is no indication that this substance is toxic," Michener said, downplaying suggestions of an anthrax scare.
The substance was found in a pile on a table in Whitby Hall and in the bottom of a mail tub in Derham Hall, Michener said.
The incident was at least the second scare involving an unknown substance found at a college in Minnesota in recent days. Officials closed off a locker room and pool areas at Southwest State University in Marshall on Saturday night after a white powdery substance was found in the men's locker room.
Southwest State authorities were still waiting Tuesday for results of tests.
