Police Chief Charlie Beck said Friday that he is sorry for the delays people endured as police searched cars and homes for the supposed gunman after school police Officer Jeffrey Stenroos said he had been shot.
Law enforcement officials now say Stenroos lied about the shooting. He has been booked for filing a false police report.
It is unclear exactly what happened in the incident outside a San Fernando Valley high school Jan. 19.
Stenroos appeared to have been shot in his bulletproof vest and authorities said that protection saved his life.
Police said Thursday they did not believe his story.
