A smart watch device and substances suspected of being illegal drugs were seized by the Shavas in a cake that was hidden in the prison near Beit Shan. The staff members, who conducted an inspection to search for drugs that had been smuggled into the walls of the prison, found a box containing the cake, hidden in a freezer in one of the Mossad's wings.
They reflected the box and later, after their suspicions grew, they decided to dismantle the cake - that's where they found the smuggled items.
