But "it was not possible yet to confirm that Mohamed Abrini indeed was the third suspect", the so-called "man in the hat" seen with the two suicide bombers at Brussels airport on March 22, the federal prosecutor's office said in a statement.
Abrini and Osama K., whom the media have identified as Osama Krayem, were among six people arrested in raids yesterday across Brussels in an important blow to the cell believed to have carried out both attacks claimed by the Islamic State group.
It said both were charged with "participation in the activities of a terrorist group and terrorist murders," the first in connection with the November 13 Paris attacks and the second in the Brussels attacks.
It said two people arrested with Abrini were released following a "thorough investigation."
Another suspect who was arrested Friday at the same time as Osama K. Was identified as 25-year-old Rwandan national Herve B.M., who is "suspected of having offered assistance to Mohamed Abrini as well as Osama K.," the statement said.
It added that another man, Bilal E.M., was charged with participating in "the activities of a terrorist group and complicity in terrorist murders" over suspicions he helped Abrini and Osama K.
