Police headquarters

The police headquarters is one of the oldest and most intricate buildings in Republic City. It serves as the base of operations for the Metalbending Police Force. Criminals in Republic City are taken here after being arrested.

History
Avatar Korra and Naga were taken here when they were arrested following an altercation with the Triple Threat Triad. Korra had an interrogation session with Lin Beifong in one of the building's many cells before Tenzin arrived to bail her out. Naga was being kept in a different part of the building with other animals and was released after Korra and Tenzin came to claim her.

After the Equalists' attack on the Pro-bending Arena, Korra, Tenzin, Hiroshi Sato, and Tahno were present at the headquarters as Chief Beifong questioned the latter two on the events they saw.

During the Battle for Republic City, Tenzin came to the police headquarters to talk to Saikhan in a communications room. The new chief was happy to see the councilman, thinking that he was captured by the Equalists too. Tenzin told him that all the other council members were taken except him. Tenzin then asked for one of the operators to send a wire to the General of the United Forces. As soon as the wire was sent, the power in the building went off and nerve gas began to fill the headquarters knocking out many people within the building. The communications room began to fill with the nerve gas coming from the vents. Tenzin told Saikhan to shut the vents and he did with his metalbending. Tenzin told everyone to stay by him while they evacuated. Tenzin then proceeded to lead everyone out by using airbending to create a spherical shield around them.

Once the group escaped the building, they were surrounded by mecha tanks. This time though, the mecha tanks had large magnets attached to their arms. The magnets were very strong, causing all of the metalbending officers to be pulled away and attached to the magnets. Tenzin tried to save Saikhan with his airbending, but the magnets were stronger, capturing Saikhan and the cops. This left Tenzin with only the operators. The airbending master put up a fight against the tanks, but was knocked into the side of the headquarters. He used his airbending to cushion his fall, yet he was still knocked out, only being able to see an Equalist vehicle drive away with Saikhan. Team Avatar came to the rescue though. Asami fought several chi-blockers, letting Tenzin free. Team Avatar and Tenzin defeated all of the attacking mecha tanks with teamwork. The group then left the headquarters due to an Equalist airship heading towards Air Temple Island.

Layout and description
The architecture of the police headquarters is comparable to that of standard Earth Kingdom buildings, as the design of both the exterior and the interior are largely comprised of geometric shapes. Located deep within Republic City, the Metalbending Police Force's base of operations is a monumental building, with numerous entrances and windows lining the exterior.

Exterior
A metal statue of Toph Beifong, the first earthbender to employ metalbending, can be seen on a pedestal high above the building's front entrance. Domes and steeples adorn the top of the structure and numerous large pillars support the roof. A platform on the highest dome seems to double as a landing pad for the police airships that monitor Republic City.

The front courtyard and streets surrounding the headquarters are lined with interconnecting metal cables supported by tall wooden poles. These cables are used by the police to zip easily around the city, as shown when they pursued Korra and Naga.

Interrogation room


Holding cells within the interior are constructed entirely of metal. A large metal table for interrogation sits in the center of each room with handcuffs on the surface to restrain prisoners during questioning. Metal panels surrounding the walls of the cell can be opened like sliding doors through the use of metalbending.

Lobby
The main lobby is located near the entrance of the building. Desks for clerks line the back of the spacious room and a rack of keys for the police vehicles hangs on the far wall. Along the sides of the room are benches for people waiting for various services from the police. In the center of the lobby floor is a slab of earth with the Republic City police emblem that is movable only by a strong stomp of earthbending.

Communications room
The communications room is a room filled with phones and other communication devices. Operators are able to contact people and get updates on activity within the city. The communications room also has metal vents hanging from the ceiling.
