Police confirmed on Monday that the dead man was a 46-year-old Nigerian of no known address. An autopsy confirmed that the stabbing was the cause of death.
The man had collapsed outside a kebab stand on the corner of Revaler Straße and Warschauer Straße in the eastern district of Friedrichshain just after midnight, police said in a statement.
Investigators are now following up leads on the killing.
Revaler Straße's many bars and clubs – and adjacent all-night kebab stands - are especially popular with young students and party tourists in the capital.
Buildings on the RAW compound – formerly train repair sheds for the East German railway operator – host cobbled-together nightspots, a climbing tower and an indoor skate park.
But the area has a dark side too, as it is well-known for street drug dealing and has seen violence in recent months.
A well-known punk band suffered a vicious knife attack there in August 2015 that left one of their musicians with a near fatal gash in his throat.
Despite an increased police presence in the area since the attack, drug dealing has continued on Revaler Straße almost uninterrupted.
