Three asylum seekers were arrested Friday on suspicion of murder after a fourth asylum seeker was fatally stabbed at a refugee centre in central Sweden, police said in a statement.
The four men - all asylum seekers - lived at the centre located near the small town of Lindesberg, about 200 kilometres west of Stockholm.
The attack is the third fatal stabbing involving asylum seekers in Sweden this year, after the country registered a record 163,000 asylum bids in 2015, straining resources and capacity at reception centres and local municipalities.
The victim sustained severe injuries to the neck and died later at the hospital, police said.
Police are interviewing the suspects, who were around 30 years old, but did not mention any motive or the nationalities of those involved.
In January, a 22-year-old woman was killed at a reception centre for unaccompanied minors near the west coast city of Gothenburg. The suspect in that case was later determined to be over 18 and is undergoing a psychiatric assessment.
A second stabbing took place on February 13 when one man was killed and three injured in connection with a fight at an asylum centre near Soderhamn, north of Stockholm. A 20-year-old man, who denies the charges, is in custody on suspicion of the stabbings.
