Missing person: 16-year-old girl in teal hoodie

I lost track of my sister, Amina Rahim, yesterday around 7:15 pm. She's 16, about 5'2", with long dark hair usually pulled into a messy bun, and she was wearing a teal hoodie, black leggings, and neon pink sneakers. Last seen outside the Worcester Public Library on Salem Street heading toward Main Street. She has a crescent moon tattoo behind her left ear and carries a bright purple backpack with a white star patch, which are two easy identifying features. I'm really worried—she's been away from home since early evening, and the area around the library can get busy after events at the DCU Center; if anyone has seen her, please contact me immediately.
