A Mesa Police crime scene technician accidentally fired a weapon that he was handling as evidence, a police spokesperson said.
Authorities initially responded to the area of Ellsworth and Brown roads around 8:30 p.m. Thursday after receiving reports of a domestic disturbance.
Once officers arrived at the scene it was discovered that a suspect fired a weapon into the air, a police spokesperson said. The man was taken into custody.
During the investigation, a crime scene tech was handling the gun. While the crime scene specialist was "securing the weapon," the gun mistakenly discharged, Mesa police confirmed.
The bullet from the gun went through the tech's hand and grazed and officer's abdomen before striking his forearm, officials said.
A second officer was hit in the nose with shrapnel which caused a "small break in the skin," police said.
Both the officers were hospitalized but have since been released.
The crime scene tech is undergoing surgery on his hand after suffering a significant injury. All three of them are expected to be OK.
Mesa Police have not released names of anyone involved in the incident.
