US detectives are investigating a knife purportedly found some time ago at the former home of OJ Simpson.

A rapidly accelerating car driven by a young man screeched across a pavement and straight into a crowd enjoying one of Southern California’s most popular boardwalks, killing one person, injuring 11 and leaving the promenade in chaos as he sped out of sight.

POLICE in riot gear and biohazard suits removed anti-Wall Street activists from an encampment outside the Los Angeles City Hall, arresting an estimated 200 people.
