The FBI is investigating how “suspicious devices” ended up on power lines near a Tyngsboro brush fire. The devices, which looked like pipe bombs, were deemed non-explosive, and there is no current evidence of terrorism, according to an FBI spokesman.
Tyngsboro firefighters discovered the devices while responding to a brush fire Wednesday afternoon. They “noticed items that didn’t appear to be part of the transmission system” and alerted National Grid, according to a statement from FBI Special Agent in Charge Harold H. Shaw.
National Grid workers investigated the devices before reporting them to police. The FBI sent special agent bomb technicians to the area, where technicians “identified multiple incendiary devices similar in structure to pipe bombs in the area,” according to Shaw.
“Early this morning, the devices were determined to be non-explosive and have been rendered safe,” said Shaw.
The FBI, Tyngsborough police, State police, and Bureau of Alcohol, Tobacco, Firearms and Explosives investigators were all at the scene Thursday morning.
The FBI alerted utility companies nationwide, but said, “At this point in time, there is no evidence which ties this incident to terrorism.”
Officials searched the area Thursday by foot and helicopter looking for more devices, according to Tyngsboro Police Chief Richard D. Howe.
