MADISON, Wis. (8/12/09)--It's hardly an epidemic, but four separate credit unions across the country this week called authorities in to inspect a variety of "suspicious packages." None of them turned out to be dangerous and apparently none are related. Two of the incidents were Tuesday in Michigan. Peoples Trust CU in Warren and Michigan First CU in Eastpointe both had authorities examine packages left outside their credit unions. Authorities determined they were not explosives. The package at Peoples Trust CU, which forced evacuation of about 50 to 60 people from the credit union area, contained trash-- a travel mug and shirt wrapped in plastic. A note with the items made it clear that the package didn't contain death threats against police officers (Detroit Free Press and The Detroit News Aug. 11). At Michigan First CU, a suspicious briefcase-type bag left outside the credit union is believed to be a service call box left by an electrician or someone working in the area, said the Free Press. The other two incidents, in Connecticut and California involved suspicious-looking powders in envelopes. Mutual Security CU, a $224.2 million asset credit union in Shelton, Conn., called the Federal Bureau of Investigation (FBI) Monday afternoon after a black powder was discovered in a letter. An employee opened the letter and the substance fell out. The employee was evaluated by emergency service personnel and did not have symptoms of illness (WSFB.com Aug. 10). Police and fire officials also were called to the credit union. The FBI took a sample of the powder and results are expected this afternoon. On Aug. 3, a mysterious white powder found inside a deposit envelope at Schools First CU, Tustin, Calif., turned out to be drywall dust. Two people were checked by paramedics as a precaution. They didn't experience illness symptoms (News Now Aug. 4 and The Orange County Register Aug. 3).
