An advocacy group for Muslims has asked the FBI to investigate an arson house fire in Hilliard as a possible hate crime. A house once occupied by an Islamic scholar was previously painted with anti-Islamic slurs. Now the Ohio chapter of the Council on American-Islamic Relations wants the FBI to look into the cause of a Monday morning fire at the house. No one was injured, but a fire official says the home sustained extensive damage. FBI Special Agent Harry Trombitas says the agency is working with Hilliard police in the investigation.
