Police arrested four youths from the city of Kalansawe Wednesday on suspicion of mugging a 91 year old woman at a Ramat Hasharon nursing home.
One of the four was an employee of the hospice, Army Radio reported.
Police said the four entered the room of the victim, who is a Holocaust survivor, stole her jewelery from her safe and then fled the scene.
After police identified the suspects, the youths returned some of the stolen jewelry.
Their remands have been extended by six days.
