CONCORD, MA (WHDH) - MBTA Transit Police detectives said that they believe two kids placed homemade explosive devices on the commuter rail tracks in Concord on Tuesday night.
Officials said crews responded to the Concord MBTA station on Sudbury Road shortly before 6 p.m. and found two bottles, one of which had ignited a brush in the area.
A bomb squad was called to the scene, but no injuries were reported.
Police said the two small bottles were filled with chemicals, creating homemade explosive devices.
One bottle exploded and caused a fire and the other was found on the train tracks.
MBTA service has resumed and commutes will not be effected.
Police said they do not believe the bottles were an act of terrorism.
