(CNN) One of two suspects in a church attack that left a priest dead in northern France was known to anti-terror authorities after attempting a trip to Syria, a French anti-terrorism prosecutor said Tuesday. Adel Kermiche, 19, was wearing an "electronic tag" during the deadly hostage incident at a Catholic church in the town of Saint-Etienne-du-Rouvray, prosecutor Francois Molins said. The monitoring apparatus was a condition of his house arrest after two attempts in 2015 to travel abroad -- at least once to Syria -- using a relative's identification, Molins said. Kermiche was identified via fingerprints after the attack, which French President Francois Hollande said was committed in the name of ISIS.One attacker was a 19-year-old wearing "electronic tag," prosecutor saysPriest killed after two men take hostages in Catholic church in Normandy, France
