A Downey mall was shut down Saturday as police attempted to calm a crowd of 2,000 teenagers arriving to see two professional skateboarders scheduled to appear at a local clothing store. Stonewood Center shopping mall, located in the 200 block of Stonewood Street, was swarmed with fans of professional skateboarders Steven Fernandez, 15, and Keelan Dadd, 27. Downey police say hundreds converged inside the shopping center while thousands formed a line outside its doors.
