JERUSALEM (VINnews) — The disappearance of an Israeli mother and daughter in Vienna took another dramatic turn Thursday as the investigation was transferred to Lahav 433, Israeli authorities intensified their search and Bank of Jerusalem shares swung sharply amid speculation surrounding the case.

The Rishon LeZion Magistrate’s Court issued a gag order Thursday at the request of Lahav 433, barring publication of details about the investigation until Sept. 13.

The investigation was transferred to Lahav 433 on Wednesday evening. Police Commissioner Danny Levy is overseeing operations from two command posts, one in Israel and one abroad, operating around the clock.

Mali Yahalomi, a manager at Bank of Jerusalem, and her daughter Liel disappeared during a trip to Vienna on Friday, Aug. 7. Their family says they had remained in regular contact throughout the trip before communications suddenly stopped.

The case has also triggered unusual activity on the Tel Aviv Stock Exchange. Bank of Jerusalem shares fell as much as 12% Thursday before recovering some of the losses and were still down about 3% amid widespread speculation over Yahalomi’s connection to the bank.

Unsubstantiated rumors circulating online suggested that bank funds could somehow be connected to the disappearance. The bank has strongly rejected any such connection.

Bank of Jerusalem CEO Yair Kaplan told employees that “aside from the fact that she is a bank employee, no connection has been found between the incident and the bank.”

The bank also conducted an internal review and said that “no findings were identified indicating any irregular activity involving the bank’s funds or assets.”

Meanwhile, investigators are pursuing multiple possibilities in Vienna.

The Israeli defense establishment currently believes there is no indication that the disappearance was nationally motivated. Three Israeli sources familiar with the investigation said extensive intelligence checks had examined the possibility of involvement by terrorist or hostile elements, with no current indication of a pro-Palestinian or Iranian cell.

Vienna police have said there is “no indication of criminal activity,” raising the possibility that the women were not abducted and may have left on their own.

Authorities are also examining whether the mother and daughter obtained a significant amount of cash before disappearing.

Phone-location data obtained by Israeli and Austrian authorities reportedly placed the women near Vienna’s train station during Shabbat. The area includes an open municipal park. Investigators are also examining whether location data may have been deleted from their phones.

The family, however, has pushed back strongly against reports suggesting investigators are leaning toward a voluntary disappearance.

“We view with great severity the briefings disseminated in recent hours, which create the impression among the public that a conclusion has already been reached,” the family said. “The family possesses information that substantially contradicts some of the claims that appeared in the reports.”

The family also said police had told them there was no unusual activity in the women’s bank accounts.

“We make it unequivocally clear that, at this stage, there is no basis for ruling out the possibility of a nationally motivated terror incident,” the family said.

Despite Vienna police saying there is currently no indication of criminal activity, authorities have elevated the investigation to the highest levels and continue examining all possibilities.

The combination of the disappearance, conflicting assessments, a sweeping gag order and the unexpected market reaction surrounding Yahalomi’s employer has added another layer of mystery to a case in which investigators have yet to publicly establish what happened to the mother and daughter.
