The suspect was alleged to have aided Abdelhamid Abaaoud (pictured), who was the mastermind of the Paris attacks in November last year

Police in Germany have arrested an Isis jihadist who aided the mastermind of the Paris atrocities after getting into Europe posing as a refugee.

German prosecutors described Bilal C as a 'scout' for the late ringleader of the November Paris attacks, Abdelhamid Abaaoud, who organised the massacres that killed 130 people.

The 20-year-old is accused of informing Abaaoud of ways to smuggle jihadists into Western Europe along the so-called Balkan route.

He had also been in touch with Moroccan fanatic Ayoub El Khazzani who opened fire on an Amsterdam-Paris train last August but was overpowered by a group of Americans and a Briton.

Bilal C was already in custody, along with an Algerian, for shoplifting and fraud in the city of Aachen.

Jailed for eight months last week he was taken from prison yesterday to be hit with terrorist charges which could see him sentenced to a much longer stretch inside.

Bilal C travelled in 2014 from Algeria via Turkey to Syria where in December he joined ISIS and received combat and weapons training in a camp run by the militants.

In June 2015 Abaaoud instructed him 'to explore the so-called Balkans route in terms of border controls and trafficking opportunities'.

The attacks in Paris in November killed 130 people and terrified France

'As a result, the accused travelled from June to August 2015 from Syria via Turkey, Greece, Serbia and Hungary to Austria' before reaching Germany, the prosecutors said.

Along the way he had informed Abaaoud of 'any open border crossings, waiting times, and arrival and departure routes.'

Several members of the ISIS group that carried out the November 13 Paris attacks are suspected of having posed as refugees.
