A  father is desperately searching for his 13-year-old daughter, who hasn't been seen since last Thursday. Melissa Borg left her Baulkham Hills home in north-west Sydney at 7:30am on Thursday in her school uniform and made her way to The Hills Sports High School in Seven Hills. However, the Year 9 student never made it to class and after her father found no sign of her when he searched their house following work, he reported his daughter missing to police. 13-year-old Melissa Borg (pictured) has been missing from her Baulkham Hills home since last Thursday . Castle Hill Police have been assisting Melissa's family with the investigation into her disappearance ever since. Melissa is described by police as being 150cm with a slim build, long brown hair and brown eyes and was last seen wearing her school uniform - a dark blue skirt and a pale blue blouse. Police have questioned her school friends about her mysterious disappearance, however they have so far been unable to find the child. Melissa's parents are extremely concerned at her out of character actions and are worried about her young age. The teenager left home at 7:30AM and made her way to The Hills Sports High School in Seven Hills . Speaking to news.com.au Inspector David Hogg said  police were holding out hope that Melissa was with friends. 'With any 13-year-old that goes missing for this time frame it's serious but our hope is she's with some friends and just doesn't want to contact her family,' Inspector Hogg said. 'If that is the case, whatever issue she has, we'd hope that she'd at least get in contact with police so we can get in contact with her family and let them know she is okay.' Inspector Hogg told the publication that there were unconfirmed sightings of the 13-year-old in the Merrylands area. However Melissa never made it to class and her father alerted police to her disappearance when he arrived home from work and she was nowhere to be found . Melissa's family and friends have taken to their Facebook pages to share a photo of the teenager in her school uniform. A picture posted online by Melissa's aunt Tricia Carlow has already been shared over 2,000 times around the Sydney area. 'My niece Melissa Borg is missing from the Baulkham Hills area since Thursday afternoon 02nd April 2015,' the caption said. 'Can you please share this around and keep an eye out for her. We at least need to know that she is safe and well.'
