CHEBOYGAN, Mich. (AP) – The FBI has said that two explosive devices recently discovered outside cell phone stores in northern Michigan are linked to letters found last month in the Upper Peninsula.
The bombs, which were discovered and defused Thursday, were found in suspicious packages left outside a Verizon store in Cheboygan and an AT&T store in Sault Ste. Married. The FBI and Michigan State Police said in a statement they believed the devices were linked to a series of letters discovered in the Upper Peninsula last month.
The letters claimed to be from the “Coalition for Moral Telecommunications” and made demands on the telecommunications companies. They have been found at several telecom tower sites, according to the FBI.
Authorities in Cheboygan said emergency personnel were dispatched around 9 a.m. Thursday after an employee reported a suspicious package near the company’s door. A bomb was found inside, which authorities removed and defused. A similar device has been reported at Sault St. Marie.
The FBI said the two devices were found in US Postal Service boxes that were sealed with black tape and placed outside stores. Each bore the inscription “CMT” and contained threatening notes addressed to mobile phone companies.
Several law enforcement agencies were investigating.
