THE suspected ISIS terrorist who plotted a terror attack at a Taylor Swift concert wanted to kill "as many possible" with a "dirty bomb".
Austrian Beran A., admitted to planning to carry out a horror attack at one of the sold-out gigs - saying he had "big plans" after he quit his job last month.
Cops foiled the ISIS-inspired terror plot finding a blue light and a siren at his home when they raided his home Wednesday.
Impersonating police is the same disgusting tactic used by far-right Norwegian mass killer Anders Breivek when he killed 77 people in 2011.
The arrest came the day before Swift's first concert of the week in Vienna after US intelligence passed information to Europol and Austrian cops.
Some 65,000 fans were expected at each of Swift's shows this week with another 20,000 gathering outside the stadium, local outlet reports.

Beran allegedly planned to carry out an attack at the sold-out gig on Thursday or Friday - with a 17-year-old and a 15-year-old acting as his accomplices.
The 19-year-old radicalized himself with the Islamic terror group's sick ideology through the internet and swore allegiance to the group's leader in a video, local media reported.
It's understood Beran planned to drive a car into the some 20,000 fans who were gathering outside Vienna's huge Ernst Happel Stadium to listen to Taylor's music during the concert.
On Thursday, Beran confessed to planning to "kill as many people as possible" outside the venue, Austrian security officials said.

He would attack those fans without tickets with knives, machetes, and explosives, .
When police raided his home they found a bomb in an "advanced" stage of development and substances and tools used to make it.
They also found ISIS propaganda, 21,000 euros in counterfeit money, machetes, and blank ammunition.
He also planned to kill himself in the attack, officials added.
The bomb squad and and police in hazmat suits were caught on video by a neighbour searching his home in Ternitz, south Austria.
A picture has emerged of Beran holding up two huge zombie knives with his arms crossed over.
Beran had until recently been doing an apprenticeship as a retail salesman in a stainless steel plant in Ternitz where his father worked.
He would have had access to the plant's laboratory, which stored various chemicals.
Security officials said the suspect recently changed his appearance and had been reading and sharing Islamist propaganda online.
Beran, thought to be the mastermind of the plot, also had a 17-year-old Austrian sidekick.
The boy - who has Turkish-Croatian roots - had been acting conspicuously near Happel Stadium, where Swift's shows had been due to take place, officials said.
A concrete threat has been averted
Franz Ruf, Austria's Director General for Public Security
He had been given a job with a company working at the stadium just a few days ago.
The third and final suspect - a 15-year-old boy - is an Austrian national with Turkish heritage, officials said.
Cops are not looking for anyone else in connection with the alleged plot.
Concert organisers said they had "no choice but to cancel the three scheduled shows" lined up for Thursday, Friday and Saturday.
American intelligence had discovered Beran A. pledged support to ISIS-K, an ugly offshoot of the death cult, on Telegram in early July.
Omar Haijawi-Pirchner, the head of the Directorate of State Security and Intelligence, said: "He was clearly radicalised in the direction of the Islamic State and thinks it is right to kill infidels."
Franz Ruf, Austria's Director General for Public Security, said: "During a raid of his home in Ternitz, south of Vienna, investigators found chemical substances and technical devices that indicated concrete preparatory acts."
Ruf said of the attack yesterday: "A concrete threat has been averted.
"The suspected perpetrator was focused on the Taylor Swift concerts. Preparatory actions were detected."

Austrian Chancellor Karl Nehammer said the cancelled shows are a "bitter disappointment" but added that a "tragedy [had been] prevented".
The Sun revealed yesterday that Taylor Swift plans to keep on working and finish the tour after the sick plot was foiled on Tuesday.
Barbaric history of ISIS
ISIS, also known as the Islamic State in Iraq and Syria, is a murderous terrorist network that officially formed in 2004.
The group, known for its barbaric public executions and beheadings, was originally part of al-Qaeda - the terrorists responsible for 9/11 which sparked the decades-long global War on Terror.
They took advantage of instability in Iraq and Syria after 2000 to rule with an iron fist.
After an injection of American troops into Iraq in 2007, ISIS lost some of its power grip in the region.
But it began to reemerge in 2011 and by 2014 the US had formed Operation Inherent Resolve.
The mission involved putting American boots on the ground in Iraq and Syria - as well as other regions in the Middle East.
In 2014, ISIS was the most powerful, best-equipped and wealthiest Islamic extremist group the world had ever seen.
By 2015 it had branches operating in at least eight other countries.
That October, their Egypt network bombed a Russian plane and killed over 220 people.
In November 2015, 130 were murdered and over 300 injured during one of their most brutal attacks on the West in Paris.
And in June 2016, a gunman who pledged himself to the murderous organisation killed at least 48 people at a nightclub in Florida.
By December 2017, ISIS had lost 95 per cent of it’s stolen territory.
But its core ideologies, which included a burning hatred for the Western way of life, continued to inspire countless terrorist attacks around the world.
While American combat in Iraq was officially axed in December 2021, 2,500 troops were left stationed there to work as advisers and trainers for Iraqi security forces trying to fend off extremist forces.
There are believed to be less than 1,000 still stationed in Syria.
Three of those American troops were killed in Jordan on January 28 - in a drone attack at a US military base near the Syrian and Iraq borders.
