Los Angeles police are investigating whether gunfire in South Los Angeles on Sunday night was aimed at two officers responding to a call, officials said Monday.
The officers were in a black-and-white patrol car driving southbound on Hoover Street near 62nd Place on Sunday night when they said they saw a muzzle flash -- the visible blast from a gun -- and determined they were being fired at, said LAPD Lt. Andy Neiman.
The officers were able to return fire, officials said.
Neiman cited the ambush killing of two New York police officers two weeks ago, saying "everyone's keenly aware of what happened in New York," and there is a "sense of uneasiness."
Initially, Deputy Chief Bob Green described the South L.A. shooting as "an ambush" targeting the officers.
"They were fired upon without any prior contact with the suspects," he said.
But on Monday afternoon, after detectives reviewed evidence, Green said the gunfire might not have been intended for the officers and related to a separate shooting in the area.
On Monday, police Chief Charlie Beck held a news conference related to the autopsy report for the the fatal officer-involved shooting on Aug. 11 of 25-year-old Ezell Ford in South L.A. Addressing the gunfire Sunday night, Beck said the gunshots came from the direction of two men and reiterated that the two officers saw muzzle fire.
"The officers believed they were the objects of an attack and returned fire," he said.
Police recovered a pistol, rifle and several shell casings, Beck said. Monday evening, the LAPD put out a statement saying that Christopher Taylor, 18, had been arrested on suspicion of shooting at an occupied vehicle. A second suspect remained at large.
The chief said "we are extremely concerned about the possibility that someone would target a uniformed Los Angeles police officer."
But Beck also noted that the neighborhood where the gunfire occurred "has been marked by gang violence, and there have been a significant number of internal gang shootings."
L.A. Mayor Eric Garcetti issued a statement saying: "Violence in our streets or against the men and women of the Los Angeles Police Department will not be tolerated. [Sunday night's] incident reminds us of the risks our officers face every day."
The alleged shooting at two police officers resulted in a citywide tactical alert and launched a massive search.
The incident prompted a statement from the Los Angeles Police Protective League, the LAPD officers' union, placing the reported shooting within the context of the release Monday of an autopsy report of the officer-involved shooting of Ford. Ford was shot three times after he allegedly struggled with two LAPD officers and attempted to remove the gun from one officer's holster.
"Last night, there was an ambush and attempted murder of two LAPD officers in 77th area by what appears to be suspects who simply wanted to kill police officers," Tyler Izen, president of the police union, said in a statement.
"This blatant violence should outrage Los Angeles residents and the community at large, as much as it does law enforcement across the nation."
About 8:30 a.m. Monday, one of the officers involved in the shooting showed multiple investigators around the crime scene. Investigators surveyed the east side of Hoover Street, where bullet casings lay.
Minutes later, investigators huddled around a gutter on the west side of the street, where they removed a weapon that appeared to be a rifle. The setting of the shooting was a South Los Angeles neighborhood with primarily single-family homes, a few churches and a nearby high school.
Christopher Oliver, 50, said that at the time of the shooting he was working on his cars in the back of his house on 62nd Place, just steps away from where investigators found shell casings early Monday.
He said all he heard was the shots -- "and you know it ain't fireworks."
He immediately "locked up everything and got in the house."
Officers arrived within minutes and blocked off the area. Oliver said his son had gone around the corner and was not allowed back to the house. "He had to spend the night at the neighbors'," Oliver said.
A three-block area around the shooting scene was immediately cordoned off after the attack as police scoured the area with search dogs.
Just before 11 p.m., the LAPD advised residents to stay indoors. "Armed suspect in the area," the police station said on Facebook. "Please keep our officers in your thoughts and prayers!"
