Missing person: 16-year-old Omar Farouk in gray hoodie

I lost my 16-year-old brother, Omar Farouk, yesterday around 3pm. He was last seen near the Illini Union on Green Street in Champaign-Urbana, walking toward Campustown. He's about 5'8" tall, athletic, with short black hair, and a small crescent-shaped scar above his right eyebrow. He was wearing a gray Nike hoodie, black jeans, and white sneakers—plus a blue backpack with a yellow zipper. This is really out of character for him, and I'm worried. If you see him, please email me at [email protected] so we can bring him home safely.
