A teenager has died following a head-on collision in Mörrum outside Karlshamn at the beginning of June, reports SVT Blekinge.
The driver of one of the cars, a man in his 40s, is suspected of gross negligence in traffic, causing bodily harm and causing another person's death.
He was not in the same car as the teenager. He was previously suspected of drunk driving. Test results have shown that he was not under the influence, says Johan Berntsson, preliminary investigation leader at the police, to TT.
Three other people were also injured in the accident. They were taken to hospital by ambulance and their condition is described as serious.
What caused the accident remains unclear.
