On Sunday, a major fight broke out between several people in Tingsryd.
One person had to be taken to hospital with stab wounds, and an 18-year-old man was arrested on suspicion of attempted murder and aggravated assault.
But on Monday evening, the 18-year-old was released by the prosecutor, and he is no longer a suspect.
The police are looking for witnesses to the fight and are continuing their investigation.
The cause of the altercation is still unknown.
