GROTON, Conn. (WTNH) — The Groton Police Department arrested a man for carrying illegal pipe bombs on Thursday.

Police responded to a medical call for a person on Gold Star Highway near Tollgate Road around 5 p.m. At the scene, officers located suspicious items inside the backpack of the person they were assisting. Police said the backpack contained what was believed to be improvised explosive devices known as pipe bombs.

Police said also inside 32-year-old Benjamin Dahm’s backpack were numerous knives and pepper spray.

After placing the package in a more secure location, Gold Star Highway near Tollgate Road was closed to traffic out of precaution.

The state police bomb squad responded to the scene and determined that the devices were actual pipe bombs and disabled them.

The bombs are no longer a threat, police said, noting that this was an isolated incident, and no injuries were reported.

Police searched a hotel room where Dahm was staying but did not find any bomb-making materials. According to police, they did find the same type of reusable plastic grocery bags that the bombs were found in.

“You don’t know where he was planning to put it. He walked right here,” said Cheryl Robishaw, Gold Star Pizza.

Dahm, was taken into custody and charged with carrying a dangerous weapon, breach of peace in the first degree, illegal bomb manufacture, illegal possession of explosives, and reckless endangerment in the first degree.

In court, the judge raised Dahm’s bond from $150,000 to $750,000.

This is an active investigation.
