During the incident, the suspect allegedly pointed the firearm at neighbors. The suspect fled into his residence before TPD’s arrival.
Officers arrived on the scene and immediately contained the suspect to his residence. The suspect refused to exit, and due to the nature of the incident, the Joint Irvine-Tustin SWAT Team responded.
