An unnamed Fall River Suspect is in custody after allegedly setting a fire inside his Tremont Street Apartment Monday afternoon, while FRFD investigators are trying to find out what triggered a fire in a basement of the former Superior Court Building on Rock Street in Fall River, which is set to be the home of a proposed Children's Museum.

Four Familes have been displaced after the Tremont Street blaze, which fire fighters discovered Monday Afternoon; those involved are being assisted by a Fall River Fire Fighters Wives Organization that began following the Hood Street Blaze in December.
