Arrested at Arlanda
On Friday, another man was arrested.
It concerns a 19-year-old who is suspected of having handled the weapon used in the murder.
- He is under arrest for a serious gun crime.
It is likely that I will request that he be detained on Monday, prosecutor Emma Berge told P4 Kronoberg.
The 19-year-old himself denies the crime.
