Initial reports loosely tied the shootings to the recent firing of officer Christopher Dorner.
“We got speculation from people that there would be reaction to that, said LAPD Cmdr. Andrew Smith. "We don’t have any information to know whether that’s true.”
After further investigation, police have determined the two are unrelated.
"There's really no indication to believe that there's any link between these two cases," Smith said.
The first shooting involved two LAPD Wilshire detectives shot at in their car during an ambush while trying to clear an entry with a key card.
The unidentified gunman shot at the officers, who were undercover working the burglary task force.
"They pulled up to the front of the gate, and as they were opening the gate, from directly behind them somebody for some reason opened fire on their car, striking it many times," Smith said.
Both men were sent to the hospital with minor injuries. They have since been released. Officials have detained 10 men for questioning, but all have been released. Another person of interest is at large.
Later that day, a gunman fired on an LAPD a county probation officer. The officer was shot in the face and has since undergone surgery in Los Angeles. He is still in the hospital in stable condition.
Police believe the second gunman is still holed up in a Willowbrook home, more than 12 hours after the shooting.
