Brussels prosecutors have charged another man with belonging to a terrorist group, the Belgian press agency Belga reported.
Belga on Sunday named the man arrested as A. Abderrahmane who prosecutors had said on Saturday was being detained for a further 24 hours after being shot during a raid in the Brussels district of Schaerbeek.
It said he was charged in connection with a related raid in France this week that authorities say foiled an apparent attack plot.
The prosecutor's office could not immediately be reached for comment.
Belgium charges three men linked to attacks in Brussels
Separately, Italian police said they arrested an Algerian man wanted by Belgian authorities for his alleged involvement in the Belgium-based network implicated in the recent attacks in Paris and Brussels.
The attacks in Paris on November 13 left 130 people dead, while the most recent attacks on March 22 in Brussels left 31 people dead, including three suicide bombers.
Several people have been arrested on terrorism charges in Belgium, France, Germany and Italy since the attack in Brussels.
Germany's Die Welt newspaper reported in its Sunday edition that European security authorities were searching for at least eight further suspects.
The men, mostly French and Belgian, were believed to be on the run in Syria or within Europe, the newspaper reported, citing security sources.
