Alleged church attacker had been arrested in Geneva
One of the two alleged attackers, who killed an 84-year-old priest and took four other people hostage at a church in a suburb of Rouen in northern France had been arrested last year in Geneva.
The 19-year-old French man, named by Prosecutor Francois Molins as Adel Kermiche, had been detained in Champ-Dollon prison before being extradited to France.

The pair, who said they were from the so-called Islamic State (IS), slit Father Jacques Hamel's throat during a morning Mass at the historic church, situated in a quiet square of St-Etienne-du-Rouvray.
Police surrounded the church and shot dead both hostage-takers.
The Tribune de Genève reports that he twice tried to get to Syria last year, first unsuccessfully via Munich, then via Geneva where he was arrested on May 14, 2015, after being expelled from Turkey.
He was held in custody for a few days in Champ-Dollon, before being released on probation and made to wear a surveillance tag.
After being extradited to France, Adel Kermiche was jailed for a year for conspiracy to prepare acts of terrorism. He was then released from prison in March this year.
