PRESQUE ISLE — Police say an officer shot and killed a man who threatened him with a knife.

Police say Brentant Lahey, 25, was fatally shot early Friday after three officers arrived at Lahey’s mobile home in response to two calls about a man threatening others with a knife.

When they got there, police said, Lahey confronted and threatened Officer Kyle White with the knife. White shot Lahey, who was pronounced dead at the scene.

The Attorney General’s Office is investigating, as it does in all cases when an officer uses deadly force.
