The shooting injury follows by two weeks the ambush shooting of two Los Angeles County Sheriffs as they sat in their patrol car in Compton, also on a Saturday night.
Both have since been discharged from the hospital.
“We can confirm that there has been an Officer-Involved Shooting at LAPD’S Harbor Station,” the department tweeted just before midnight Saturday, Los Angeles time, without providing more details.
The officer was in stable condition, Police Chief Michel Moore tweeted.
Los Angeles City Councilmember Joe Buscaino tweeted that he was headed to the hospital.
Soon afterward the councilmember told the CBS affiliate in Los Angeles that the officer is expected to be fine after suffering a graze wound to the head.
“This is a reminder of the danger of police work in our city, in our state, in our region,” Buscaino told the station.
“Thankfully, he’s going to be okay.”
