QUESTIONAL Forces troops have arrested a suspected ISIS supporter for a pathway to track high-speed trains in Europe.
The 42-year-old Iraqis living in Vienna are said to have twice stretched steel cables across and across tracks in neighboring Germany.
Austrian police said in both cases that an "intruder" had mixed the tracks in an attempt to cause a fatal and shocking trace.
The terror plot follows an al-Qaeda appeal calling on its fanatical supporters to track "vulnerable" trains and arrive days after ISIS was crushed in Syria.
The description of last year's alleged plot said German police a steel cable was stretched over tracks on a track between Nuremberg and Munich.
Concrete blocks were also placed on and near the rails two months later, although no one was injured.
On October 7, a high-speed intercity Express (ICE) tree had run over the obstacles, even though it was astonishing, it was only minor damage.
A threatening letter written in Arabic was found near the attack site as well as writings related to ISIS.
Two months later, the Berlin police reported a similar attack on a railway line in Karlshorst's suburb.
They found damage to the superheader and similar writings in Arabic as well as an ISIS flag.
Local newspaper Kronen Zeitung reports the five-year-old for 15 years in the Iraqi army and lived in Austria as a refugee while working for a security company.
The 42-year-old was arrested on Monday, and the prosecutors said he was suspected of "performing tea-terrorist attacks on railway lines in Germany in October and December 2018."
Prosecutors said in custody detention was suspected being murdered, causing serious damage to property, membership of a terrorist organization and dangerous interference in rail traffic.
Bavarian Interior Minister Joachim Herrmann allegedly claimed the "excellent international cooperation" in a press release and said the survey was "in full swing" to establish facts.
The attack comes just days after German police were arrested 10 people suspected of planning an Islamist attack.
