Police continue to search for two additional suspects.
Both suspects, aged 27 and 20, were arrested by police in Stockholm on Friday and Saturday. On Saturday, they were transported north to Sundsvall where they will be questioned by police.
“They are two of those who were at the scene of the crime. We’re looking for two more who were also involved in the matter,” said Västernorrland police spokesperson Christer Johansson to the TT news agency.
Early in the morning of Christmas Eve, police received a report of a stabbing in an apartment used by the Swedish Migration Board (Migrationsverket) in the Fagerdal residential area of Sundsvall.
In the apartment, police found a 36-year-old man dead and another man injured.
“We’re hoping that he can identify those who’ve been arrested,” said Johansson.
Police on Södermalm in Stockholm received a tip at the weekend from someone who claimed to know who was involved in the killing.
The tipster’s account supported the story police received from the injured man found in the apartment by police.
Johansson told TT on Friday that the injured man told police that he and the murder victim were attacked by three of four men who forced themselves into the apartment.
The man said he became frightened and fled into a neighbouring apartment at which point he then called police.
Police have also found the murder weapon, but refused to comment on to a motive for the attack.
“That isn’t something we’re going to get into,” said Johansson.
