Authorities are investigating a "suspicious" fire that ripped through a South Philadelphia rowhouse Friday, injuring two adults and a child forced to flee the blaze.
Police at the same time credited one of their own - Lt. Jonathan Josey - with rushing into the burning building to alert residents.
Early Friday evening, police said they had a male in custody and charges were expected. No further information on the suspect was available.
The Fire Department said the blaze, on the 1700 block of Sigel Street, was reported shortly before 6:15 a.m. and witnesses told investigators they saw someone throw something into the house.
