A relative of one of the jihadist killers of journalists at French satirical magazine Charlie Hebdo has been arrested in Turkey on his way to Syria, according to a judicial source cited by Agence France Presse on Sunday. The source said Mourad Hamyd, brother-in-law of Cherif Kouachi who was behind the January 2015 attack in Paris that killed 12, was detained in Turkey last month.

Hamyd, wrongly identified on social media in the aftermath of the attack as being one of three Charlie Hebdo killers, was denied entry to Turkey and sent to a detention centre in Bulgaria on July 28. The source said French anti-terrorist investigators are preparing a European arrest warrant for Hamyd, whose sister was Cherif Kouachi's wife. Hamyd came under initial suspicion of acting as the getaway driver for Cherif and his brother Said, and he was briefly detained before being released without charge.
