The interior ministry opened a probe into Thursday's murder of the 22-year-old who suffered "three fatal bullet wounds" as she drove through the capital's Camp Sarah district.
Fares, a fashionista with 2.7 million followers on Instagram for her pictures sporting tattoos, different hair colours and adventurous clothes, was a victim of her fame and targeted because of her lifestyle, Twitter users wrote.
