A 45-50 year-old man was found by police late on Saturday night dead in an apartment in the western Stockholm suburb.
Police had been called to the scene by neighbours who responded to screaming and shouting in the apartment.
“Two people are arrested and detained on suspicion of murder,” said Gert Fredlin at Stockholm police to news agency TT.
The men were still in the apartment when the police arrived but were so inebriated that no sensible information could be solicited from them.
A knife was found outside of the apartment block. Police were on Sunday unable to confirm if it was the murder weapon.
Police are reticent over the details of the case, in part out of respect to the relatives of the deceased.
