RITTMAN -- A small house fire early Tuesday morning in Rittman was contained to the basement of a house where police broke up a meth lab operation last week.
The fire started at about 3 a.m. on Liberty Street at a house that was originally believe to be unoccupied.
Once at the scene, fire crews found three people were in the basement when the fire started.
The house did have a meth lab at one point, but those suspects were in jail at the time of the fire.
Fire crews believe the meth lab had nothing to do with the fire and do not know for sure why the three people were in the basement of the abandoned home.
Fire investigators are working to determine a cause.
