BANGOR — A fatal stabbing in Bangor last month has been ruled a case of self-defense, and prosecutors have decided not to press charges.

Police say 34-year-old Jeffrey Leblanc was stabbed once in the abdomen at a city home in the early morning hours of Dec. 29. He was taken to a hospital where he later died.

Police say Leblanc was a guest in the home and assaulted a resident, causing facial injuries. The resident tried to fend off Leblanc, who continued assaulting the person. Finally, the resident stabbed Leblanc.

The case is closed.

Police say Leblanc had been at the hospital just hours before the stabbing, after being seen covered in blood in the street trying to enter homes and moving vehicles. Leblanc left the hospital after refusing treatment.
