New EU rules for prisoner transfers introduced last year mean the 23-year-old Osama Krayem's wish is likely to be granted after a legal process that is expected to last around a year, the radio station reports.
Krayem’s lawyer did not confirm the information received.
Osama Krayem, 23, from Malmö, was charged on April 9th with “terrorist murders” over last month's suicide blasts in the Belgian capital.
The coordinated bombings at Brussels airport and a metro station near European Union headquarters, claimed by Isis, left 32 people dead months after the Paris attacks killed 130 people.
Belgian authorities suspect Krayem, a Swede of Syrian origin, of buying the bags used for the Brussels bombings.
He was filmed on CCTV with Maalbeek metro station bomber Khalid El Bakraoui minutes before the bomb went off.
Krayem's lawyer Vincent Lurquin told reporters that his client had also planned to blow himself up but decided not to go ahead with it.
Three men detonated suicide bombs in Belgium's worst-ever terror attack: brothers Ibrahim and Khalid El Bakraoui and Najim Laachroui.
A fourth man, Mohamed Abrini, the so-called “man in the hat” who accompanied the two airport bombers but did not detonate his own device, was arrested in Brussels on April 8th. He has also been charged over the Paris attacks.
Initial investigations suggest that the Brussels attackers had planned to hit France, but with police on their trail, decided Belgium was an easier target.
