The officer involved in a fatal shooting at the Corner Alley Uptown Saturday night, has been identified.

The officer has been identified as 26-year police department veteran, Sgt. Dean Graziolli.

According to reports, Graziolli broke up a fight between a group of men inside the bowling alley and escorted several of them out of the establishment around 9 p.m.

One of the men, a 21-year-old, returned and was "combatant and viciously attacking" Graziolli, according to Cleveland FOP President Brian Betley.

After an alleged assault, shots were fired and the victim was transported to University Hospitals, where he later died.

Witnesses at the scene tell WKYC that blood could be seen on the officer's face.

Joshua Duke posted video of the moments after the shooting occurred on Facebook. Joshua's sister, Rochelle Duke, said she and others at the establishment stepped in to apply pressure to the 21-year-old's wound until paramedics arrived.

Graziolli was also taken to University Hospitals and suffers contusions, bruises, and stitches in the mouth.

He is on a three-day paid administrative leave as the investigation continues.
