The San Diego Police Department Chief Shelley Zimmerman said the officers belonging to the Elite Gang Unit were conducting a traffic stop before the firing.
The officers stopped their car and called for additional reinforcements when they heard shots being fired. When the other officers arrived they found both policemen with bullet wounds.
The police officer with multiple wounds was taken to Scripps Mercy hospital in Hillcrest but he did not survive. The other officer is admitted at the hospital and is undergoing surgery.
Zimmerman refused to give details about the deceased officer but mentioned that he is survived by his wife and children.
The police soon launched a hunt for the suspects and asked residents of 3800 block Boston Avenue to stay indoors.
The search led to the arrest of a suspect who has not yet been identified. Helicopters, SWAT vehicles, patrol cars were dispatched to assist in the combing operation for more suspects.
The reason of the firing or descriptions of the possible suspects still remains unknown.
The shooting in San Deigo has further escalated fears as it follows recent attacks on police at Dallas and Baton Rouge, Louisiana.
