Heavily armed Swat teams supported by hundreds of other officers have detained 14 people suspected of having ties to Islamic State in early-morning raids in Austria.
An earlier statement from the public prosecutor’s office in Graz had spoken of eight arrests in twin operations there and in Vienna involving 800 police.
But justice ministry official Christian Pilnacek later said the discrepancy was between the eight arrest warrants issued and the 14 people – 11 men and three women – actually detained.
Besides suspected links to IS, Mr Pilnacek said those detained were being investigated for attempts to try to set up a “parallel society … an attempt to create a kind of theocracy in Austria”.
Two of the 12 locations raided were mosques, he said.
The police sweep comes less than a week after police in Vienna detained a 17-year-old they describe as belonging to “radical Salafist” circles who they said has confessed to experimenting with building a bomb.
But the prosecutor’s statement said Thursday’s operation had been planned for “a longer time”, suggesting no immediate link.
Mr Pilnacek did not rule out some overlap to Mirsad Omerovic, a Serbian-born Islamic cleric sentenced last year in Graz to 20 years in prison for recruiting dozens of young men to fight for IS.
But he said he could not say there was a “direct connection” in the cases of all of those detained.
Most of them, including some with Austrian nationality, had Balkan antecedents, he said.
Konrad Kogler, Austria’s chief security official, told reporters that data from about 140 mobile phones and other electronic devices must be evaluated, meaning “weeks and months of work ahead of us”.
Austria has not experienced the attacks that have rocked other nations in Europe.
But interior ministry figures show that approximately 300 people have left or tried to leave Austria to fight for radical groups in the Middle East since 2012.
Of these, 90 have returned while 50 are listed as having been killed in fighting.
