A man, now the third in two weeks, died in Gothenburg and was found with knife wounds on Monday.
His death becomes the third in 14 days, raising fears that a lot needs to be done to stop the attacks.
He was found with injuries from a stabbing and was rushed to hospital where he later died.
No one has been arrested but police are investigating.
An 18 year-old man died on July 17th after he was stabbed during a robbery, and just four days later a 19-year-old was stabbed during a brawl at a shopping centre and later died of his injuries.
Three people have been arrested on suspicions of murder and robbery in connection to the first death while another man was detained on suspicion of murder in relation to the second.
Justice Minister Morgan Johansson early this year said the government would consider stricter laws for knife crime.
