Deputy chief prosecutor Ove Jäverfelt sent the lawsuit to the Södertörn District Court on Thursday morning, reports Ekot.
The 18-year-old who is suspected of murder denies the criminal charges, but admits that he test-fired a weapon that prosecutors say was used, according to the channel.
A further four other people are charged as suspects in the case. Three teenagers are charged in the case, suspected of gross protection of a criminal. A fourth person is suspected of aiding and abetting the gross protection of a criminal.
All deny wrongdoing.
It was on April 10 this year that Mikael was shot to death at an underpass in Skärholmen, after a confrontation with some young people. Mikael was on his way to the swimming pool with his son when he was shot with two shots. According to Ekot, the prosecutor sees the crime as particularly reckless due to the fact that Mikael was shot in front of his son.
