It was determined to be a case of arson after a shed in the 800 block of East  Vermilion Street burned down.

Lafayette Fire Department Spokesman Alton Trahan says that firefighters battled the blaze just before three o'clock yesterday afternoon.

Police have arrested 19-year-old Otis Key along with 18-year-old Katherine Cass on a charge of negligent arson.

Fire officials say it only took about ten minutes for them to get the blaze under control, but there was significant damage to the shed behind a building at the address.

Both the business and shed were vacant.
