Investigators say a man involved in a shooting at a gate outside the Navy's submarine base in Connecticut lunged at one police officer with a knife and then stabbed another in the thigh before an officer opened fire.

The defendant, Gary Ray Brunache, appeared Friday in U.S. District Court in Hartford on the charge of assaulting a federal officer. He did not enter a plea and his attorney declined to speak with reporters.

Federal authorities say an officer fired approximately three shots at Brunache but he was not hit by any of the rounds.

The Naval Criminal Investigative Service says Brunache told them that he walked from his home in Norwich to see his brother on the base in Groton and became agitated when police denied him entry.
