Police: 2 juveniles responsible for incendiary devices found near Commuter Rail tracks

CONCORD, Mass. — MBTA Transit Police detectives have identified two juveniles responsible for incendiary devices placed near train tracks in Concord, police said early Wednesday morning.

The two devices were placed near the train tracks in Concord Tuesday, prompting a bomb squad response and major delays on the Commuter Rail.

According to police, they initially responded for a brush fire. When officers arrived at the scene, they discovered two devices investigators referred to as incendiary, or capable of causing fires.

The devices were made up of a plastic bottle that contained two liquid chemicals that can be purchased over the counter -- when the chemicals interact with each other for long enough, they heat up and cause a flash fire. The devices were found 15 feet apart.

Investigators ruled out terrorism.

"There is a connection between the devices and the brush fires," he said. "It's important to note this is not an act of terrorism, this is not related to terrorism."

According to police, the two juveniles responsible, aged 14 and 15, are set to appear in court. The two will be summoned for possession of incendiary devices and interfering with public transportation.

All Commuter Rail trains were stopped during Tuesday's investigation. Full service has since resumed.
