“My immediate reaction is that this is unacceptable, but we must sit down and discuss how we should proceed,” Eriksson's lawyer, Björn Sandin, told TT.
Eriksson was arrested in Stockholm in March and faced a number of charges, including blackmail and aggravated assault.
But the court dismissed the majority of those brought against the former leader of the Uppsala Maffia, a criminal network active in Sweden in the early 1990s.
Eriksson had been released from custody by late June when the trial against him and the other suspects concluded.
A co-defendant in the case was sentenced to eight months in prison while another man received probation. Five other co-defendants were also acquitted of all charges.
Back in 2006, Eriksson, referred to in Sweden as "Tjock Steffe" or "Fat Steffe", made headlines around the world when he slammed an exclusive Ferrari Enzo in near Malibu in California.
The crash had a number of mysterious circumstances, with Eriksson claiming to have been a passenger and authorities never locating the supposed driver.
Eriksson was later arrested on suspicions of embezzlement, auto theft, drunken driving, and cocaine and weapons possession.
