The brother of Toulouse killer Mohamed Merah has been charged with complicity in the murders and involvement with terrorism.
Abdelkader Merah went before an anti-terrorism judge near Paris after four days of preliminary interrogations.
Prosecutors say they have “serious and corroborating” evidence linking the 29-year-old to the crimes. Abdelkader was arrested while a 32 hour siege was underway at his brother’s apartment following the killing of seven people in three separate attacks.
In France, being placed under formal investigation is the next legal step after being held in custody and means that a criminal trial is likely.
Abdelkader is suspected of playing a role in providing logistical support to his brother and was already known to security services for helping to smuggle militants into Iraq.
Mohamed Merah was killed by a sniper on Thursday after a siege and gun battle with police.
Abdelkader told police that he was proud of his 23-year-old brother’s killing spree.
His partner was released overnight.
