Amra was found guilty of burglary on May 10 and indicted by the Marseille prosecutor’s office for kidnapping leading to death.
His lawyer, Hugues Vigier, told French news channel BFMTV “that he would like to believe that he (Amra) was not aware of the planned release.”
“For me, this project does not correspond to what I know about him. If he is behind all this, it is because I have not understood who he is,” added Mr. Vigier.
According to some French media reports, externalAmra had tried to escape from her cell earlier this week by trying to saw through the cell bars.
Ms Beccuau, the capital’s prosecutor, told a news conference that Amra had 13 convictions, the first dating back to October 2009, when he was 15.
Although the man, now aged 30, was not a “closely supervised detainee”, the Paris prosecutor clarified that his transport required a “level three escort”.
Amra is believed to have links to a gang in the southern city of Marseille, plagued by drug-related gang violence.
But his criminal record to date does not contain any convictions for drug-related offenses, the Paris prosecutor’s office said on Tuesday.
