The attempted murder took place in an apartment in Örnsköldsvik.
According to the prosecutor, the accused cut the victim with a knife on the arm and shoulder while another knife was held against the victim's neck.
The accused also aimed an electric shock weapon at the victim and forced a pair of headphones, a razor and a wallet during what the prosecutor classifies as attempted murder.
Aggravated robbery
The trio is also charged with aggravated robbery when they assaulted another person who was in the apartment in connection with the attempted murder.
The victim's hands and feet were tied, whereupon he was stabbed and cut with a knife.
At the same time, they forced the victim's cell phone.
Another assassination attempt the next day
One of the suspects is also charged with another attempted murder and aggravated assault in an apartment in Eskilstuna.
