State police arrested a 56-year-old South Windsor woman accused of having a loaded gun in her carry-on bag at Bradley International Airport.
Police said Marie Westbrook was going through the security checkpoint on Wednesday afternoon with a carry-on bag.
As it was going through the screening machine, a TSA official noticed a pistol inside the bag, police said.
State police responded, seized the bag and found a loaded handgun inside.
Westbrook has a valid permit for the weapon, according to police, but flying with one in carry-on luggage is not permitted.
TSA requires anyone traveling with a firearm to pack it in checked luggage and declare it when checking in. The gun cannot be loaded.
Police took the gun and charged Westbrook with circumventing airport security.
Westbrook was released on a $2,500 bond and will be in court at the end of the month.
NBC Connecticut went to her house on Thursday morning, but there was no answer.
