The Philadelphia Police Department has opened an investigation into two arson incidents that occurred at the same residence on the 8200 block of Williams Avenue in the Cedarbrook neighborhood. The first fire was reported around 7 p.m. on the evening of September 21, 2026, and a second blaze was set on September 25, 2026.
Both incidents resulted in no injuries, but the repeated targeting of the same address prompted law enforcement to treat the events as arson and begin a formal inquiry.
