As Sarah Kreager, 26, tried to sit down on a Baltimore City bus Tuesday, police say, a middle-schooler told her she couldn?t. When she attempted to take another seat, a middle-schooler wouldn?t let her. Finally, according to police, Kreager just sat down.

She was “immediately attacked” by nine students ? three females and six males ? from Robert Poole Middle School. They punched and kicked her at 2:59 p.m. at the intersection of 33rd Street and Chestnut Avenue, according to Maryland Transit Administration police.
