Police have arrested a 20-year-old man on suspicion of preparing a terrorist attack on a synagogue in Heemstede, near Haarlem, in March.
The man, who was detained on 9 June, is suspected of preparing a bombing or arson attack, acting as part of a group and with a terrorist motive, the public prosecution service (OM) said. He was remanded for a further 14 days by an Amsterdam judge on Friday.
Police and prosecutors believe a synagogue near the Adriaan Pauwlaan was the target of an imminent explosion, which officers prevented.
He is the latest person to be held in the case. Officers picked up two Amsterdam boys aged 14 and 17 near the same synagogue on the night of 19 to 20 March, after finding powerful fireworks nearby, and arrested an 18-year-old from Amsterdam a week later.
The Heemstede plot was one of a series of attacks on Jewish sites in the Netherlands this spring, including an arson at a synagogue in Rotterdam and explosions outside a Jewish school and an office complex in Amsterdam.
Four young men have admitted carrying out the Rotterdam attack but told the court they did not know the building was a synagogue. Prosecutors say it was a deliberate act of terrorism.
The justice ministry raised its annual budget for protecting Jewish buildings to €2 million in April following the attacks.
