Oukabir was born in Morocco in 1989, police sources have told OkDiaro in Spain.
But a Facebook page with Oukabir‘s name – which has since been deleted – identifies him as being from Marseille and living in Ripoll in Catalonia.
His wall has been flooded with angry messages following the attack. On Tuesday he uploaded a picture of himself relaxing on a beach, although the location is not immediately clear.
Police are understood to have made an arrest following the attack, but the suspect has not yet been identified.
