ST. PAUL (AP) -- A mysterious, jelly-like substance found at the Science Museum of Minnesota was not hazardous, police and public health officials said Friday.
The museum, which had been closed for two days while authorities investigated the incident, was scheduled to reopen Saturday.
The substance, which is still unidentified, was found Wednesday when police were notified about a man who left an unattended briefcase at the popular attraction. A book found in the bag aroused suspicion. Police Chief William Finney said the book was "germane to current world events."
The seven-story museum was evacuated and closed Wednesday afternoon. A bomb unit was called to the museum, but no explosives were found.
Preliminary tests indicated the substance was not anthrax.
