The suspect, who police believe received military training in Syria, crouches in front of grenades, machine guns, gun cartridges and a tactical helmet and military-style webbing and a backpack.

He is wearing a headband with Arabic writing similar to those widely worn by ISIS militants and combat fatigues.

The man, whose identity has not been given by police, reportedly arrived in Germany with his family at the end of 2015.

Police said he had applied for asylum with his family, claiming to be a Syrian fleeing the country’s civil war.

In fact, they believe he was part of a terror cell aiming to massacre civilians.

His wife was also taken into custody during the raid.

They were among three suspects arrested as 450 heavily-armed police officers raided properties, including two refugee centres, across Germany on Thursday, DailyMail reported.
