SOUTHBURY, Conn. -- State police said they received a call Sunday from a man who said he had encountered an intruder at his house.

He stated that he encountered a man who had entered the basement. The man advanced in the direction of the Nagy, and Nagy said he shot his gun in the direction of the intruder and left his home to wait for police.
