(Pawtucket, RI) -- Two people are under arrest after a fire destroyed an old mill building in Pawtucket last week. Police say Joseph Green was treated for non-life-threatening injuries at Rhode Island Hospital after they responded to Collyer Park on Mineral Spring for a call of a man lighting himself on fire just before midnight on Friday. An acquaintance, Meagan Gammage, was reportedly taken to Miriam Hospital for smoke inhalation. Both reportedly had previous warrants out for their arrests. Firefighters had to go back to the mill on Friday after the fire reportedly re-ignited in the roof.
