An American Airlines plane at Sky Harbor was forced to evacuate after a passenger boarding the plane discovered a single bullet on the ground.  Sergeant Vince Lewis says the passenger alerted  the pilot who decided to clear the plan.  The passengers were bused to another location where they were rescreened. 

Lewis says the bullet was a 22 caliber and no one is claiming ownership.  The plane originated in San Jose before landing in Phoenix where it was heading to Minneapolis.  Police are questioning former passengers about the bullet.  The passengers reboarded without incident.
