The 31-year-old suspect is a resident of Norsborg south of Stockholm and has been wanted on an arrest warrant since September 27th suspected of aggravated robbery.
The man was arrested around 6pm on Monday evening in Stockholm after turning himself in voluntarily.
“We’ve held a short introductory interview with him in which he denies committing any crime. We plan to hold a more in-depth interrogation in the afternoon after which I’m going to decide what should happen with his continued detention,” prosecutor Leif Görtz told the TT news agency.
Görtz refused to say exactly what the 31-year-old is suspected of doing or what evidence there is against him.
The suspect is known to police for having committed previous offences.
In February 2005, the 31-year-old was sentenced to two-and-a-half years in prison by the Nacka District Court for helping plan the robbery of an amoured car a year earlier in Fisksätra centrum in Nacka, southeast of Stockholm.
The Svea Court of Appeal altered the conviction, however, and in May 2005 sentenced the man to six months in prison for preparation to commit a theft.
The court ruled that there was insufficient evidence to prove that the plans made by the 31-year-old and his accomplice were really in preparation for a robbery.
Five other men have already been remanded in custody for their suspected involvement in the spectacular robbery of the G4S cash depot.
Three other suspects have been taken in for questioning and then released.
