Dutch police, acting on intelligence provided by the secret service, have detained five suspects for allegedly plotting a possible terrorist attack.
According to a statement issued by the national prosecutor's office, the arrests were made on Friday after investigators received information about an imminent terrorist attack.
It said: "The five are suspected of preparing an explosion, being members of a criminal organisation and forging passports."
No details were released about a possible target or how the attack was to be carried out. The identities of those arrested were also kept secret and a prosecution spokesman declined to give further details.
The suspects were detained in four Dutch cities and brought before a district judge today.
One was released due to lack of evidence and the remaining four had their custody extended by 10 days, the statement said.
Investigators confiscated computers, computer discs, video tapes, cassettes, a fake driver's licence and a fake passport during raids at the suspects' homes.
The suspects are from Amsterdam, Amersfoort, The Hague and Schiedam, prosecutors said.
