On Sunday, the officers arrived at their accommodations, a former asylum center comprised of prefabricated homes in Bad Segeberg, around 60 km from Hamburg. In the evening, they held a party to celebrate their arrival and two officers' birthdays.
According to reports, two officers at the party had sex in public, others urinated against a fence and one policewoman did a striptease on a table with her service weapons.
A spokesperson for the Hamburg police said the behavior of the officers was "unacceptable."
"The police chief has decided to dismiss these squads, which have not yet been deployed in Hamburg, with immediate effect. These police units are now back in Berlin. The police chief has made it clear that such behavior is unacceptable for police officers."

The Berliner Zeitung newspaper possesses photographs of the party.
Berlin police spokesman Thomas Neuendorf confirmed the report.
"Hamburg police have informed us that our colleagues are being sent back. There are allegations that they urinated in public, that sexual intercourse was conducted in public and a policewoman danced on the table in a bathrobe with her service weapon. It is clear that there was a lot of alcohol," he told Sputnik Deutschland.
Neuendorf compared their conduct to that of teenagers on a school trip and said an investigation is underway with disciplinary measures to follow.
"This is not a class trip, where 16-year-old schoolchildren sometimes get carried away. These are officials who have to uphold the reputation of the entire police force. They cannot behave like that!"
"This is misconduct and will lead to disciplinary action. So far, there are no indications that criminal acts were committed. Ultimately, it depends on what individual officials are demonstrated to have done. The measures range from a reprimand to a fine or an order that an officer can no longer take part in large squads on assignments."
In total, approximately 1,000 Berlin officers are supposed to be assisting their colleagues in Schleswig-Holstein with security for the conference.
Earlier this month, German police introduced temporary border controls until July 11 to help prevent disturbances at the summit. The German federal government is spending €32 million ($36 million) on extra security for the conference.
Extra police have been drafted as thousands of protestors are expected to descend on Hamburg to protest the summit. Last week, a court in Hamburg granted a request by the organizers of a 3,000-tent protest camp to allow them to occupy Hamburg's city park for the duration of the summit. The authorities are expecting as many as 30 demonstrations to take place, with some still locked in legal disputes.
