Ossama Krayem is now charged in Paris and Brussels attacks

A spokesman for Belgian prosecutor's office says Krayem was "omnipresent"

Brussels, Belgium CNN  — 

Brussels terror suspect Ossama Krayem, already charged in connection with the March 22 attack that killed 32 people in the Belgian capital, was formally accused Wednesday with involvement in the November attacks in Paris.

Prosecutors accused Krayem, 23, with terrorist murder and participation in the activities of a terrorist group in the Paris attacks. A judge also extended his detention for an additional month.

Krayem can be placed in most of the safe houses used to prepare for both attacks, according to Eric Van Der Sijpt, a spokesman for the federal prosecutor’s office in Belgium.

He called Krayem “omnipresent.”

Among other locations, prosecutors say Krayem can be tied to a Brussels apartment believed to have been used to make suicide vests for the Paris attackers.

Prosecutors said Krayem had traveled to Belgium from Germany in October in a car rented by Salah Abdeslam, the Paris attacks suspect who eluded authorities for months until his March arrest in Belgium.

Krayem, who has also known by the names Naim al Hamed and Omar Abdelkader, was arrested April 8, the same day Brussels and Paris terror suspect Mohamed Abrini was arrested in a separate raid. Krayem was charged at that time with involvement in the Brussels attacks.

Surveillance cameras captured him buying bags used to carry explosives detonated at the Brussels Airport, and during the attack at a subway station in the city.

All told, 32 people died and 270 were hurt in the Brussels attacks. The Paris attacks left 130 people dead.

Krayem is a Swedish citizen who was known to counterterrorism services there, according to Magnus Ranstorp, a Swedish counterterrorism expert at the Swedish National Defense College.

He posted images of himself from Syria with automatic weapons and the ISIS flag, Ranstorp said. The final post he made on Facebook from Syria was in January 2015.
