Two Injured in Mesa Shooting Involving Off-Duty Police Officer and Security Guard Outside Reception Hall

A late-night confrontation outside a Mesa reception hall ended in gunfire early Saturday morning, leaving two people injured after an armed juvenile allegedly opened fire on a security guard and an off-duty Mesa Police officer became involved in the shooting.

According to the Mesa Police Department, the incident occurred at approximately 1:05 a.m. on October 10, 2026, outside Versalles Reception Hall near Main Street and Lazona Drive in Mesa, where a private event was taking place.  

Both injured individuals were transported to local hospitals with non-life-threatening injuries.

Mesa Police say the incident began when a juvenile male attempted to enter the reception hall but was denied entry.

Investigators say the juvenile then pulled out a handgun, pointed it at a security guard, and fired at him.

Following the initial gunfire, the juvenile reportedly ran toward a nearby vehicle.

Police say the security guard and an off-duty Mesa Police officer followed the juvenile and both discharged their firearms at him.

The juvenile then fled south across Main Street.

As the juvenile crossed Main Street, an on-duty Mesa Police patrol officer encountered him.

According to investigators, the juvenile removed a handgun and threw it onto the ground before being taken into custody without further incident.

Police say the juvenile suffered apparent gunshot wounds and was transported to a local hospital with injuries that were not considered life-threatening.

An adult male who was inside a vehicle associated with the juvenile was also struck by gunfire. He was transported to a local hospital with non-life-threatening injuries.

Neither the off-duty Mesa Police officer nor the security guard was injured. Authorities also reported no injuries to bystanders.
