A storm on Sunday brought lightning that is blamed for starting a fire that caused a Swansea retirement home to be evacuated.
About 90 residents of the Grand Manor home at 58 Frank Scott Parkway East evacuated the residence just before 1 p.m., according to fire department reports.
Residents heard a loud boom and then the fire alarm sounded.
The strike caused a hole in the roof and ignited a small fire in the attic. Firefighters contained the flames and all but one resident were able to return to their rooms. That room had smoke and fire damage.
