German police said they are unable to confirm reports that a 17-year-old refugee died after being urged to throw himself from an apartment block by onlookers.
The Somali teenager, who had just returned from a psychiatric clinic, suffered fatal injuries in a fall on Friday in the eastern town of Schmoelln.
Thuringia state police said those interviewed included first responders, staff at the migrant home where the teenager lived and others.
Schmoelln’s mayor, Sven Schrade, said he had heard accounts of people shouting: "Go on, jump!".
He later described the claims as "unconfirmed".
Separately, police are investigating whether to bring criminal charges over social media posts which appeared to celebrate the teenager’s death.
