The firm that secured a nine-figure settlement in a building collapse in Philadelphia has filed a lawsuit in the city’s Common Pleas Court over the deadly 2017 fire in London’s Grenfell Tower apartment building.

The June 2017 fire engulfed the 24-story building in the north Kensington area of west London and left 72 dead, as well as 70 injured. Friday will mark the two-year anniversary of the disaster. The Pennsylvania statute of limitations would run on that date.
