Prosecutors announced Wednesday an off-duty Los Angeles police officer who fired a gun during a scuffle with a 13-year-old boy will not face any criminal charges.

The fight in the Anaheim front yard of Officer Kevin Ferguson 11 months ago was captured on two widely circulated videos that spurred heated anti-police protests in the city.

Orange County District Attorney Tony Rackauckus is held a morning news conference to say Ferguson would not face charges.

The videos showed Ferguson exchanging angry words with several teenagers who had walked across his lawn. The argument turned physical with the 13-year-old, and Ferguson pulled out a gun and fired it into the ground, sending the teens running and screaming.

The officer alleged that he feared for his life because he believed the teen threatened to shoot him.

"I didn't say that. Why are you lying? I said I was going to sue," the teen can be heard saying in a video.

No one was seriously hurt.

The boy and one other teen were arrested but Ferguson was not, fueling the anger of hundreds of protesters who took to the streets in the nights that followed. Dozens were arrested after blocking traffic.

Ferguson's attorney Larry Hanna has said Ferguson feared for his own and his sick father's safety because of the teens, who he had reported to police before.

Investigators said they treated the officer like any other civilian and concluded he made a citizen's arrest.

Ferguson was pulled from the street and put on desk duty for the LAPD at the time. It's not clear what his current status is.

Police have not released the boy's name because he is a minor.

The boy's family have filed a lawsuit against Ferguson, the city of Anaheim and LAPD.
