The unlawful assembly order was issued about 8:15 p.m. Tuesday, according to Deputy Trina Schrader of the Los Angeles County Sheriff's Department. No injuries were reported.
What the arrests were for and suspect information were not immediately available, Deputy James Nagao said.
This was the fourth consecutive night demonstrators gathered outside the station, located at 1310 W. Imperial Highway, to protest the Aug. 31 shooting during a confrontation with deputies near West 109th Place and South Budlong Avenue.
Kizzee was shot and killed after he was stopped for an alleged vehicle code violation while he was riding a bicycle.

After he was stopped, he allegedly tried to run away.
"Our suspect was holding some items of clothing in his hands, punched one of the officers in the face and dropped the items in his hands," Lt. Brandon Dean said. "The deputies noticed that inside the clothing items that he dropped was a black, semiautomatic handgun, at which time, a deputy-involved shooting occurred."
The sheriff's department alleged that Kizzee "made a motion toward the firearm."
Kizzee was struck more than once by the gunfire. He died at the scene.
