Four people were hospitalized after jumping from the second story of a Pasadena apartment building that caught fire Monday morning.
The fire started at about 2 a.m. in the rear unit of a fourplex located in the 200 block of East Penn Street, according to Lisa Derderian of the Pasadena Fire Department.
All of the units quickly became involved in the blaze and several residents had to jump from the second floor to escape the fire, Derderian said.
Four people were transported to local hospitals with minor injuries they received when jumping from the building, Derderian said.
One person was reported to have been trapped in the building, but fire crews did not find anyone during a sweep of the structure.
East Penn Street between North Summit Avenue and North Marengo Road had to be closed while crews worked to extinguish the blaze.
The fire was declared a knock down at about 2:20 a.m., according to Derderian.
Red Cross workers were on hand to help those who were displaced by the fire.
The cause of the blaze was under investigation.
