A bank customer who spotted a man with a concealed weapon inside a TD Bank branch in Glastonbury, Connecticut, thought he was doing the right thing by bringing the bank staff's attention to a potential robbery in progress.
Gursky, 50, was inside the bank on Monday when he noticed a man who had a gun tucked underneath his shirt.
Sensing imminent danger, Gursky approached the teller and said the word "gun."
Feeling his warning was not getting through, Gursky began writing a note to explain the situation.
Police arrived on the scene and determined that the suspicious man was a law enforcement official who was permitted to carry a concealed weapon.
Officers then tracked down Gursky, who blamed the whole thing on "miscommunication."
Gursky was arrested and charged but was later released on a promise to appear in court next Wednesday.
