Missing teen, gray hoodie, red backpack

I lost my younger brother Malik Ahmed, 16, yesterday around 3pm in Grand Rapids. He was wearing a gray hoodie, black jeans, and a red backpack with a small scratch on the bottom corner. He has a crescent-shaped freckle on his left cheek and a small scar above his right eyebrow. Last seen near the Grand Rapids Public Library on Library Street, walking toward Wealthy Street by the river, then heading toward Riverfront Plaza. He’s shy and can be disoriented in crowds; he goes by Mali with close friends. We’re really worried and just want him safe. If you spot him, please notify me through the app.
