A 33-year-old man arrested in Groton after police said they discovered pipe bombs in a backpack he was carrying has been restored to competency, court records show.

Benjamin Dahm appeared in New London Superior Court on Tuesday and his attorney, Michael Miller, said a Dec. 4 report indicates Dahm is now competent to stand trial. Dahm previously was deemed not competent to stand trial — unable to assist in his own defense — and sent for treatment at Whiting Forensic Hospital in Middletown.

Now that he is competent, Dahm will be transferred back to prison while his criminal cases are pending. Dahm faces charges that include illegal bomb manufacturing and illegal possession of explosives in connection with the arrest in Groton.

On Oct. 20, 2022, police said Dahn overdosed at the Star Discount Liquor Store at 518 Gold Star Highway. It was there that police said they found the backpack containing two pipe bombs.

Dahm has numerous other pending criminal cases, including one stemming from a September 2021 incident in which he was found shirtless inside an Old Lyme home.
