A man aged 20 and a 17-year-old girl from The Hague have been arrested on suspicion of helping a 15-year-old girl travel to Syria, Nos television said on Wednesday afternoon.
Police managed to stop the girl before she got on a plane for the civil war-torn country after friends warned them about the plan.
The investigation into the girl’s plans led the police to the couple, who were arrested early on Tuesday morning.
Last May, a tip-off from the Dutch security service AIVD led police to stop a 16-year-old would-be jihadist leaving the country to fight in Syria.
That girl had turned up in connection with an investigation into people actively recruiting youngsters to join the armed struggle in Syria.
The national counter-terrorism office said last year some 100 Dutch youngsters have left the country to take part in jihadist missions.
