With anti-riot vans and helmeted paramilitary forces, police in China's capital have smothered a southern district for a second day after a protest by hundreds of migrant workers. The move underscores Beijing's sensitivity over unrest fueled by anger over social inequality.

The heavy police presence Thursday around a bustling wholesale clothing market in Beijing's Fengtai district was imposed a day after hundreds of migrants rallied outside the building over the death of a 22-year-old woman from the central province of Anhui.

The woman, Yuan Liya, had worked in the mall selling clothing until her body was found Friday near the exit of an underground parking garage.

Police have ruled the death a suicide, but protesters believe she may have been slain and say the investigation has been poorly handled.
