CINCINNATI (AP) -- A prosecutor says Cincinnati police did not break any laws when an officer fatally shot a man who authorities say pulled a knife on another officer.

Hamilton County prosecutor Joe Deters says police were justified when Sergeant Andrew Mitchell shot 40-year-old David Hebert (AY'- behr) on April 18.

Deters says Hebert refused orders to stop reaching into his pocket as police questioned him about a reported stabbing. Deters says Mitchell fired two shots after Hebert pulled a knife with a 6-inch blade and stepped toward another officer. Hebert was struck in the arm and chest and died at the scene.

Deters says Hebert, of Cincinnati, had a blood alcohol content of .33, more than four times the legal driving limit. Hebert also had marijuana and hallucinogenic mushrooms in his system.
