After what they thought was a seven-hour standoff with an armed suspect, an Arcadia (Calif.) Police Department SWAT team stormed a house to discover the man they were looking for left before police arrived, the Pasadena Star-News reports.
Police received a call from a resident of the home who said someone inside his house had a gun. Police arrived and set up a containment area around the house. A hostage negotiator and SWAT members attempted unsuccessfully to make contact with the suspect. A camera-equipped robot was sent in through the front window to search for the gunman.
