The two suspects are 38 and 19 years old.
Police spokesperson Lars-Håkan Lindholm says that the first police car at the scene suspected the men, among other things due to reports by witnesses. He says that this might be an honor related act of violence. It has not been substantiated, but this is one of the theories the police are working with.
Two men have been held in connection with the death of a 16-year-old girl in Malmö.
The girl believed to have been pushed from a balcony in an apartment block in the city's Hermodsdal district on Sunday evening.
The suspects, both of whom are related to the victim, were arrested near the building and taken in for overnight questioning.
On Monday morning the public prosecutor ordered for them to be detained in custody on suspicion of murder or manslaughter.
"They deny committing an offence," police spokesman Lars Karsten told TT.
Neighbours questioned by police said that there often appeared to be trouble in the fourth floor apartment.
"A lot of people have complained about noise and screaming," one neighbour told Sydsvenskan.
