Wembley Stadium Security Keys Go Missing

So police may have misplaced a set of keys for massive Olympic venue Wembley Stadium—but that doesn't mean there's anything to worry about, says Scotland Yard. Authorities are pretty sure the keys were simply misplaced, and not stolen—and are reasonably certain they haven't fallen into the wrong hands. But just to be certain, the locks have been changed, said officials. The set of "internal security keys" for Wembley went missing early last week as police were finalizing security procedures, reports AP. They spent days retracing their steps trying to locate them, but didn't have any luck. (More 2012 London Olympics stories.)
