Police want to speak to driver of a silver hatchback with red P-plates as they search for missing Hunters Hill 14-year-old Krystal Muhieddine THE driver of a silver-coloured hatchback with red P-plates may hold the key to finding a teenage girl who ran away from her northern Sydney home on Tuesday. Krystal Muhieddine, 14, hasn't been heard from since she took a green school bag containing clothes and cash from her Hunters Hill home on Mount St at 5.30am on Tuesday without telling her family where she was going. Krystal failed to attend school that day or return home and there are serious concerns for her welfare. Krystal Muhieddine, 14, left her home on Mount Street without telling her family where she was going. Police believe Krystal was picked up near her home on Tuesday morning by someone driving a silver-coloured hatchback with red P-plates on it. Ryde Police said this morning detectives would be trying to track down the owner of the car and there had been no developments since an appeal was issued last night. Krystal is described as being of Mediterranean/Middle Eastern appearance, 180cm tall with a thin build, shoulder-length brown curly hair, black-framed reading glasses and wearing a dark navy blue hooded top. Anyone who sights Krystal or has information about her whereabouts is asked to contact Crime Stoppers on 1800 333 000.
