LEWISTON – For the second time in less than a month, Zachary Duprey was the victim of a stabbing in downtown Lewiston.

Police said the 21-year-old Lewiston resident was stabbed twice in the back early Tuesday at Del’s Bar & Grille.

Duprey was treated at Central Maine Medical Center and then released. It was not clear what led to the stabbing, and police said the investigation was continuing.

Duprey was stabbed twice in the thigh on Oct. 30 while in a street fight with another man.

Police said a third man who jumped in and stabbed Duprey was later charged with elevated aggravated assault.
