On 3-5-10 at around 8:23pm Alhambra Fire personnel arrived on scene of a one story commercial structure at 2620 W. Concord with light smoke showing.  A 2nd alarm was soon requested as fire breached the roof.  A quick knockdown was achieved, however, with no injuries reported.  Units from Pasadena, San Marino and Monterey Park assisted.  Although I wasn’t far away, I missed most of the action on this one.
