Police are currently searching for and appealing for public assistance to help locate missing girl Rukaiya.
The 14-year-old was seen in Dallas about 9.10am on Saturday, 25 January.
Police and family have concerns for Rukaiya's welfare due to her age, her disappearance being out of character, and her diagnosis of autism spectrum disorder.
Rukaiya is about 152cm tall, with a medium build, and long, dark hair.
She was last seen wearing silver glasses, grey tracksuit pants, a grey hoodie, and was carrying a Coles shopping bag wrapped in a striped light-coloured top.
Investigators have released an image of Rukaiya in the hope someone recognises her and can provide information regarding her current whereabouts.
She is most likely travelling on foot or by public transport and is known to frequent parks and creeks in the Dallas area.
Anyone who sights Rukaiya or with information is urged to contact Tripe Zero (000) or Broadmeadows Police Station on (03) 9302 8222.
