The Ninjago City Police Station is the headquarters of the Ninjago City Police, located in Ninjago City.
The Police Commissioner holds a press conference in front of the station on the sightings of the Ninja after they're proclaimed public enemy number one as well as confiscated all of their vehicles. He soon went inside where he hires Ronin to capture the Ninja. After Ronin succeeds he holds another conference while the officers escort the Ninja on a prison bus.
Cole and Zane enter the police station in order to interrogate Luke Cunningham.
When Harumi was arrested, she was brought to the interrogation room, where she remains silent before a stolen garbage truck rammed the front of the station. The police were all shocked to see it was Garmadon before he injured and maybe killed many officers so he could break Harumi out. The Commissioner told the Ninja about the attack as the officers were cleaning up.
In need of a quest, the Ninja decide to help the Ninjago Police and spend the day on nothing but false leads, rescuing cats out of trees, repairing faults, cleaning, and sorting out files, until they eventually give up.
