At eight o'clock that evening, Mielke and Ziemer waited in a doorway as Captain Anlauf, Sergeant Willig, and Captain Franz Lenck walked toward the Babylon Cinema, which was located at the corner of Bülowplatz and Kaiser-Wilhelm-Straße.
As they reached the door of the movie house, the policemen heard someone scream, "Schweinebacke!"

As Captain Anlauf turned toward the sound, Mielke and Ziemer opened fire at point blank range.
Sergeant Willig was wounded in the left arm and the stomach.
However, he managed to draw his Luger pistol and fired a full magazine at the assailants.
Captain Franz Lenck was shot in the chest and fell dead in front of the entrance.
Willig crawled over and cradled the head of Captain Anlauf, who had taken two bullets in the neck.
As his life drained away, the Captain gasped, "Wiedersehen... Gruss..." ("So Long... Goodbye...").

Meanwhile, Mielke and Ziemer made their escape by running into the theater and out an emergency exit.
They tossed their pistols over a fence, where they were later found by Homicide Detectives from the elite Mordkommission.
Mielke and Ziemer then returned to their homes.

According to Koehler, "Back at Bülowplatz, the killings had triggered a major police action.
At least a thousand officers poured into the square, and a bloody street battle ensued.
Rocks and bricks were hurled from the rooftops.
Communist gunmen fired indiscriminately from the roofs of surrounding apartment houses.
As darkness fell, police searchlights illuminated the buildings.
Using megaphones, officers shouted, 'Clear the streets!
Move away from the windows!
We are returning fire!'
By now the rabble had fled the square, but shooting continued as riot squads combed the tenements, arresting hundreds of residents suspected of having fired weapons.
The battle lasted until one o'clock the next morning.
In addition to the two police officers, the casualties included one Communist who died of a gunshot wound and seventeen others who were seriously wounded."

Captain Anlauf's wife had died three weeks earlier of kidney failure.
The KPD's murder of Captain Anlauf thus left their three daughters as orphans.
The Captain's oldest daughter was forced to drastically rush her planned wedding in order to keep her sisters from being put in an orphanage.
Captain Franz Lenck was survived by his wife.
Senior Sergeant Max Willig was hospitalized for fourteen weeks, but made a full recovery and returned to active duty.
In recognition for Willig's courage, the Berlin Police promoted him to Lieutenant.

After the murders, the act was celebrated at the Lichtenberger Hof, a favorite beer hall of the Rotfrontkämpferbund, where Mielke boasted: "Today we celebrate a job that I pulled!" (
German: "Heute wird ein Ding gefeiert, das ich gedreht habe!")
