Nuclear whistleblower Mordechai Vanunu has been arrested for violating a ban on contact with foreigners.
His lawyer said he was detained over a romance with a Norwegian woman rather than for revealing nuclear secrets.
“She is not interested in nuclear business,” his attorney, Avigdor Feldman, told reporters.
“She's interested in [him... and he] is probably interested in her.”
A Jerusalem court ordered that Mr Vanunu, who was taken into police custody on Monday, be put under house arrest for three days pending an indictment.
