Israeli police have arrested former nuclear assistant Mordechai Vanunu on charges of having contact with "a number of foreigners" at a hotel in Jeruselum Al-Quds.
"Vanunu was detained in Jerusalem last night," said Police spokesman Micky Rosenfeld. "He is suspected of having had contacts with foreign agents."
A court spokesman said he would be released from jail Tuesday evening but was ordered to stay under house arrest through Thursday.
Vanunu has been detained several times for violating the terms of his parole which ban him from travel or contact with foreigners.
He served an 18-year sentence in prison after discussing his work as a technician at Israel’s Dimona nuclear reactor with a British newspaper in 1986.
After his release in 2004, Israel’s Supreme Court barred him from travelling abroad, alleging he has more details on the Dimona atomic reactor to divulge.
Vanunu however denies he poses a security risk but says he will pursue anti-nuclear activities and wants to live abroad.
The restrictions on him have been condemned by international human rights groups.
