Something did not look right when the luggage was going through the x-ray machine at Bradley International Airport.
It was a gun, a semi-automatic, according to state police and the man accused of transporting the weapon has been arrested.
Whether the firearm was in carry-on luggage or checked luggage, police could not say.
Airport security called police and Delgado was charged with circumventing airport security, refusal to submit fingerprints, interfering with a police officer and alteration of firearm identification marks, the Hartford Courant reports .
Rather than heading to Puerto Rico, Delgado was held on $25,000 bail and was scheduled to appear in court Thursday, according to the Courant.
